Question

PLS HELP!!!

A triangular prism. The rectangular sides are 12 feet by 3 feet, 12 feet by 5 feet, and 12 feet by 4 feet. The 2 triangular sides have a base of 3 feet and height of 4 feet. The area of each triangular base is: A = 1/2(b)(h) A = 1/2(3)(4) A = ft2 There are two bases, so total base area is ft2. The lateral area is: A = (12)(3) + 12(5) + 12(4) A = ft2 The total surface area is ft2.

Answer 1

The lateral area is 144 ft^2

The Total surface area is 156ft^2

Answer 2

6, 12, 144, 156

Explanation:

The area of each triangular base is: A = 1/2(b)(h) A = 1/2(3)(4) A = 6 ft2

There are two bases, so total base area is 12 ft2.

The lateral area is: A = (12)(3) + 12(5) + 12(4) A = 144 ft2

The total surface area is 156 ft2.
