Question

what is the volume of the rectangular prism? = 1 cubic inch a 78 cubic inches b 94 cubic inches c 188 cubic inches d 168 cubic inches

Explanation:

Step1: Count dimensions

Count the length, width and height of the rectangular - prism in terms of the number of 1 - cubic - inch cubes. Assume the length $l = 7$ inches, width $w = 4$ inches and height $h = 6$ inches.

Step2: Apply volume formula

The volume formula of a rectangular prism is $V=l\times w\times h$. Substitute $l = 7$, $w = 4$ and $h = 6$ into the formula: $V=7\times4\times6$.

Step3: Calculate result

$7\times4\times6=(7\times4)\times6 = 28\times6=168$ cubic inches.

Answer:

D. 168 cubic inches
