Question

What is the volume of the box pictured below?

fractions 3 and 1 over 10 cubic feet
fraction 3 and 2 over 5 cubic feet
fraction 6 and 5 over 8 cubic feet
fraction 8 and 3 over 4 cubic feet

Answer 1

Answer is 8 3/4 cubic feet
(The last answer choice)

V= L x W x H

4/5 x 3 1/8 x 3 1/2

I prefer to change these into mixed fractions first.

4/5 x 25/8 x 7/2 = 35/4, simplified to 8 3/4
