If the circumference of the bottom surface is 20 cm and the length of the side edge is 8 cm, then its side area is: 20 8 = 160 square centimeters.

Features: 1) The cuboid has 6 faces. Each set of opposite faces is identical.

2) The cuboid has 12 edges, and the opposite four edges are of equal length. According to the length, it can be divided into three groups, each group has 4 edges.

3) The box has 8 vertices. Each vertex connects three edges. The three edges are called the length, width, and height of the cuboid.

4) The two adjacent edges of the box are perpendicular to each other.

If the circumference of the bottom surface is 20 cm and the length of the side edge is 8 cm, then what is its side area?

20 8 = 160 square centimeters.

If the circumference of the bottom surface is 20 cm and the length of the side edge is 8 cm, then what is its side area?

20*8=160 square centimeters.

Quadrangular prism base edge length = 20 4 = 5

The sum of the area of all sides = 4 4 9 = 72 square centimeters.

Summary. The side area of a straight quadrangular prism is equal to the bottom circumference multiplied by the side edge length, and if the bottom circumference of a straight quadrangular prism is 30 cm and the measuring prism length is eight cm, then the side area of 30x8 is equal to 160 square centimeters.

If the circumference of the bottom of a straight quadrangular prism is 30 centimeters, the lateral area of 30x8 is equal to 160 square centimeters.

Why multiply.

It's 240, and you can take a straight prism and turn it into a rectangle, long for the base circumference and wide for the length of the edge. Thank you.

The bottom side length of the quadrangular pyramid is 2 cm, so the bottom surface is 2 = 2 2 = 4 square centimeters.

The length of the side edge is 5 cm, and the bottom edge is 2 cm of the isosceles champling triangle, so the area = 1 2 2 2 6 = 2 6 square centimeters, so the surface area = 8 6 + 4 square centimeters.

Summary. Hello, glad to answer for you. <>

The bottom side is two centimeters long, the side edges are five centimeters long, the surface area of the regular quadrangular pyramid is about square centimeters, and the volume is about cubic centimeters. <>

First, the height of this regular quadrangular pyramid can be calculated according to the Pythagorean theorem, then the side area of the regular quadrangular pyramid can be calculated, then the surface area of the regular quadrangular pyramid can be calculated, and finally the volume of the regular quadrangular pyramid can be calculated. <>

The formula for calculating the surface area is: s=a +4 [1 2a (h +a 4)=a +a (4h +a). S pyramid surface area = S pyramid side + S bottom area.

Volume v = 1 3a h. Surface area s=a+4 [1 2a (h + a 4) = a +a (4h + a).

Find the bottom side length of two centimeters, the side edge length of five centimeters, the side area of the regular quadrangular pyramid, surface area and volume.

Find the bottom side length of two centimeters, the side edge length of five centimeters, the side area of the regular quadrangular pyramid, surface area and volume.

Hello, glad to answer for you. <>

The bottom side is two centimeters long, the side edge is five centimeters long, the surface area of the regular quadrangular pyramid is about square centimeters, and the volume is about cubic centimeters. <>

Firstly, according to the Pythagorean theorem, the matching height of this regular quadrangular pyramid can be calculated, then the side area of the regular quadrangular pyramid can be calculated, the surface area of the regular quadrangular pyramid can be calculated, and finally the volume of the regular quadrangular pyramid can be calculated. <>

The formula for calculating the surface area is: s=a +4 [1 2a (h +a 4)=a +a (4h +a). S pyramid surface area = S pyramid side + S bottom area.

Volume v = 1 3a h. Surface defect product s=a +4 [1 2a (h + a 4) = a +a (4h +a).

40 4 = 10 (cm), 10 10 = 100 (imitation slag clear square centimeter), A: its edge length is 10 centimeters, and the bottom area of the preparation is 100 square centimeters

So the answer is: 10 centimeters, 100 square centimeters

1, it should be a straight seven hunger buried prism, right? If so, each side is a rectangular cleft with a side area of s=2*6*7=84(cm) 2, a total of 7 congruent rectangles.

2. It will form a rectangular box without a lid, with a rectangular bottom of the draft a=12-2-2=8cm, a width of b=8-2-2=4cm, a height of c=2cm, and a volume of v=abc=8*4*2=64cm 3

The volume of this container is 64cm3
