Question

A 10-inch by 10-inch plece of cardboard has a 2-inch by 2-inch square cut out of
each comer. The sides are then folded up to make a box without a lid. What is the
volume of the box?

Answer 1

Equation for volume of a square is V=BH or V=LWH

if 2 inches are cut from each corner it decreases the size from 10 by 10 to 6 by 6

the 2 inches that were cut of now represent the height

so...

L=6

W=6

H=2

sub this into the formula to get L=6x6x2 which equals to 72 inches squared
