Anonymous users2024-02-071, to the 3rd power is equal to the second question, 1 liter is equal to 1 cubic decimeter, and 1 cubic decimeter is equal to 1000 cubic centimeters. Therefore, 24 liters is equal to 24,000 cubic centimeters, and if the water depth is h, then there is an equation 40*25*h=24000 (* represents multiplication) to get h as 24 centimeters. Question 3 s = 3 thousand divided by 40 equals 75 centimeters.

Anonymous users2024-01-25Since the entire sheet is used, the surface area should be subtracted from the area of the rectangle by the area of 4 small squares. i.e.: s = 30 25 5 5 4 650 square centimeters;
Volume is the volume, length multiplied by width multiplied by height. i.e. v = (30 5 2) (25 5 2) 5 = 1500 square centimeters.
