You could break it up into two different rectangles, one with the sides of 8ft x 4 ft x 2 ft the second being 3 ft x 2 ft x 2ft.

But then what would I do after ?

Luigi0210:

Find each individual volume, and then simply add them together.

chuckthedonut:

8 x 4 x 2 = 64

8 x 4 x 2 = 64
and 6 x 2 x 2 = 12

so now I just add those together?

Luigi0210:

Yup, and that should give the volume for the shape.

The answer is 76 then.

tyyy !!

Are you sure it is, someone else says it's 100.

yellojang:

the general formula of volume is length x width x height though

yellojang:

so if u think about it (6 x 3 x 2) + (5 x 4 x 2) -> 36 + 40 = 76 u can also do it reverse which is (8 x 6 x 2) - (3 x 2 x 5) = 76
