Question

Bill has a box of markers that has a base of 8 cm by 20 cm and a height of 6 cm. Martin's pencil box has a height of 4 cm and a base that is 15 cm by 16 cm. Bill says his marker box has the same volume as Martin's pencil box. Is Bill right? Explain

Answer 1

Bill is correct because  to find the volume of a rectangular prism you have to find the area of the base which is length times width and then you have to multiply it by the height. I did that with the two boxes of makers and the both equal 960 cm cubed, which means bill was right.  

Answer 2

Ok so you need to multiply the length, width, and height together for each one.
Bill: 8 x 20 x 6 = 960
Martin: 4 x 15 x 16 = 960
So Bill is right, they both have the same volume.
