Question

2. A refrigerator box measures 11 feet by 6

feet by 6 feet. Sam decides to fill up the box
three-fourths with trash. How much space will the
trash take up?

Answer 1

297 cubic feet

Explanation:

1. Find total volume of the box: V=lwh

l=11 ft, w=6 ft, h=6 ft (doesn't matter which is which in this case)

V=(11 ft)(6 ft)(6 ft)

V=396 cubic feet

2. Find volume of 3/4 of the box

Multiple the total volume by 3/4: what you are doing is diving the volume into four parts and only taking three of them since that is how much will be filled up with trash.

3/4V=x, V=396 cubic feet

3/4(396) = 3(396)/4 = 1188/4 = 297 cubic feet
