Two rectangular prisms have the same volume. The area of the base, B, of the blue prism is 418 square units. The area of the bas
kenny6666 [7]

Answer:

The height of the blue prism is half the height of the red prism

Step-by-step explanation:

Represent the volume of the blue prism with Vb and the red prism with Vr

So, we have:

V_r = V_b

A_b = 418 --- base area of the blue

A_r = \frac{1}{2}A_b --- base area of the red

Required

Determine which statement about the heights of the prisms is true

Volume is calculated as:

Volume = Base\ Area * Height

For the blue prism:

V_b = A_b * h_b

For the red prism

V_r = A_r * h_r

Equate both volumes

V_r = V_b

A_r * h_r = A_b * h_b

Substitute the expression for A_r

\frac{1}{2}A_b * h_r = A_b * h_b

Divide both sides by A_b

\frac{1}{2} h_r =  h_b

<em>This implies that the height of the blue prism is half the height of the red prism</em>

area = 7 * 1.5/2

area = 10.5/2

area = 5.25 square units

Answer: B. 5.25 square units
