The volume of a rectangular solid is 180 cubic centimeters. The length is 10 centimeters and the width is 4 centimeters. Using the formulas V=lwh, what is the solid in centimeters?
I would solve this problem like this:
V=180
l=10
w=4
h=?
plug l, w, and v into the equation, v=lwh: 180=10•4•h
Solve:
180=40•h
180/40=40h/40
4.5=h
So, h=4.5
You can check by plugging in 4.5 for h in the original equation:
10•4•4.5=180
hope that helps :)
