Answer:

Option B. 2376 Square feet

Step-by-step explanation:

The following were obtained obtained from the question:

Base (B) = 24ft

Length (L) = 40ft

Height (H) = 9ft

Slant height (S) = 15ft

Surface Area (A) =?

The surface area (A) for triangular prism is given below:

A = BH + 2LS + LB

Where:

B is the Base

L is the Length

H is the Height

S is the Slant Height

A is the Surface Area

Using the above equation, the surface area can be obtained as follow:

A = BH + 2LS + LB

A = (24x9) + (2x40x15) + (40x24)

A = 216 + 1200 + 960

A = 2376 ft2
