Question

Suppose we have 10 rectangular prisms stacked on top of each other, as shown in the figure. Each one has l = 5 cm, w = 6 cm and h = 2 cm. What would be the total volume of the rectangular prism if none of the sections were staggered?

A) 60 cm^3


B) 300 cm^3  
C) 450 cm^3
D) 600 cm^3

I put A as my first choice but it was wrong.

PLEASE HELP ME!!!

Answer 1

D, there are 10, 60 is the volume for one

Answer 2

D

Explanation:

Volume of rectangular prism is given by the formula:

Volume of Rectangular Prism = Length * Width * Height

Thus,

Volume of single rectangular prism =
`length*width*height\\=5*6*2\\=60`

60 is the volume of 1 of these rectangular prisms, so 10 of these would have a volume of
`10*60=600`

Answer choice D is right.
