Answer: 400 square meters

First, find the lateral area. The area of a rectangle = b*h

Normally we do one lateral face at a time, but the prism’s base is an equilateral triangle, so the bases of all the lateral faces are all
12 m by 10 m. Therefore, the area of each lateral face is 120 square meters, totaling 360 square meters.

Next, find the area of the prism’s bases. The area of a triangle is 1/2 * bh. For the bases, the base is 10 m and the height is 4 m.

1/2(10)(4) = 20

Since there are two bases, they add up to 40 square meters.

Add the lateral area and the bases’ area:

360 + 40 = 400 square meters
