Use the pythagorean theorem.
The length is 6.2
the width is 3.5
the height is 10
So the volume =217cm^3
I hope this help
The answer is $12,052.5. youd divide 800 into 1500 then you multiply the answer you get by 6400 then add (1500/100) x 3.5 to get your answer.
I think C... I'm guessing cause my math is wrong
