Question

A rectangular prism is 4 meters long, 5 meters wide, and has a height of 7 meters. What is its volume?

1.140 m3
2.166 m3
3.84 m3
4.70 m3

Answer 1

So 4×5×7 so 4×5=20 and 20×7=140 so 140 is the answer

Answer 2

The volume of a rectangular prism is found with the formula
V = w · l · h
So if you substitute those variables for the dimensions of the prism you get
V = 5 · 4 · 7
Then you simplify
V = 20 · 7
V = 140

Therefore, the volume of the prism is answer choice 1, 140 meters³
