WILL GIVE THE BRAINLEST Find the surface area of the triangular prism

fomenos

Answer:

460 mi²

Step-by-step explanation:

The surface area consists of 3 rectangles of the sides, and the two base triangles.

The front rectangle has dimensions of 10x11, so it's area is 110 in²

The left side rectangle has dimensions of 10x11, so it's area is 110 in²

The right side rectangle has dimensions of 12x11, so it's area is 132 in²

The top and bottom triangles have a base of 12 and a height of 8, so their area is

A = (1/2)(12)(8) = 108/2, but there are 2 of them, so their combined area is (108/2)(2) = 108 in²

The total surface area is 110 + 110 + 132 + 108 = 460 mi²
