Exercise 14 Page 329

Remember the formula for the volume of a prism.

252 m^3 or 12 12 m^3 or 12.5 m^3

Practice makes perfect

We will calculate the volume of the prism. Let's see the given measurements on the rectangular prism.

The volume of a rectangular prism with length l, width w, and height h can be calculated using the following formula. V=l wh We are given that l= 2 45, w= 1 37, and h= 3 18. Let's substitute these values into the formula for the volume of a prism!

V=l wh

a bc=a* c+b/c

V=2* 5+4/5 (1* 7 +3/7) (3* 8+1/8)

Multiply

V=10+4/5 (7 +3/7) (24+1/8)
