I need help ill give brainiest

Answer 1

Answer:

9 ft

Step-by-step explanation:

its volume is equal to the area by height;

(2.5 x 3)h = 67.5

h = 9ft

Answer 2

Given:

Volume of triangular prism is 67.5 cubic feet

Height of triangular prism is 3 feet

Base width of triangular prism is 5 feet

Length of triangular prism is 't'

To find:

Value of 't'

Steps:

The formula for volume of triangular prism is,

volume of triangular prism = $\frac{1}{2}$ × Width × Height × Length

67.5 = $\frac{1}{2}$ × 5 × 3 × t

67.5 = $\frac{1}{2}$ × 15 × t

$\frac{67.5}{15} = \frac{t}{2}$

$4.5 = \frac{t}{2}$

$4.5 * 2 = t$

$9 = t$

$t = 9$

Therefore the value of 't' is D) 9 feet
