Question

find the volume of the right rectangular prism the numbers are b = 21 cm2 and h = 3cm
A. 1,323 cm3
B. 441 cm3
C. 63 cm3
D. 189 cm3

Answer 1

The formula for the volume of a rectangular prism is V = l * w * h, where l is the length, w is the width, and h is the height.

Given that the base area (b) is 21 cm^2 and the height (h) is 3 cm, we can solve for the volume.

Since the base area is the product of the length and width (b = l * w = 21 cm^2), we can find the length (l) or width (w) using this information.

Let's assume the length is the larger value so that l > w.

If we set w = 1 cm, then l = 21 cm^2 / 1 cm = 21 cm

Now, we can calculate the volume:

V = l * w * h
V = 21 cm * 1 cm * 3 cm
V = 63 cm^3

Therefore, the volume of the right rectangular prism is 63 cm^3.

The correct answer is:
C. 63 cm3
