Answer 2

5

Answer 3

area*height=volume

Answer 4

The equation to find the volume of a rectangle is LengthxWidthxHeight=Volume to solve back track. We already know what LengthxWidth is, as that is the formula to find the area of the rectangle which is 20cm^2 so now we just have to find the height.
20xheight=100, 100=the Volume
(20xheight)/20=100/20 divide 20 from both sides
height=5
so the answer is 5cm

Answer 5

V = base * height
->h = V/ base = 100/ 20 = 5 cm
