-16t^2+400=0
16t^2=400
take square root on both sides.
4t=20
t=20/4
t=5

The volume of the prism is 9 in³.
<h3 /><h3>What is a prism?</h3>
A prism is a 3-dimensional shape, with two identical shapes facing each other.
To calculate the volume of the prism, we use the formula below.
Formula:
- The volume of the prism (V) = 72×volume of one cube
- V = 72L³............. Equation 1
Where:
- V = Volume of the prism
- L = Length of the cube
From the question,
Given:
Substitute these values into equation 1
- V = 72(1/2)³
- V = 72(1/8)
- V = 9 in³
Hence, the volume of the prism is 9 in³.
