Use the image to answer the question. Find the volume of the right rectangular prism. (h = 3 cm, b = 21 cm2)
63 cm3
1,323 cm
3441 cm3
189 cm3
The volume of a rectangular prism is found by multiplying the length, width, and height.
Volume = length x width x height
The length and width are not given in the image, but the base area (b) is given as 21 cm^2. The formula for the base area of a rectangular prism is length x width, so we can find the width by dividing the base area by the length.
21 cm^2 = length x width
21 cm^2 = 7 cm x width
Width = 3 cm
Now we can find the volume:
Volume = 7 cm x 3 cm x 3 cm = 63 cm^3
Therefore, the volume of the right rectangular prism is 63 cm^3. The correct answer is 63 cm3.
