Answer:
62 units
Explanation:
A solid is composed of squares and equilateral triangles. Its net is shown below:
A triangular prism and its net are shown. The net is three squares with side length 4 units. Attached above and below the middle square are equal sized triangles.
The area of each triangle is 7 square units. The surface area of the triangular prism is _____ square units
surface area = area of squares x area of triangles
area of square = length²
4² = 16
there are 3 squares, total area = 16 x 3 = 48
there are 2 triangles = 2x 7 = 14
14 + 48 = 62
