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. (input whole number only.)

62

Step-by-step explanation:

The side length of each of the three squares is 4 units.  This means the area of each would be 4² = 16 sq. units.  For the three, this means the total area is 16(3) = 48 sq. units.

The area of each triangle is 7 sq. units; this means together the area of the two triangles is 2(7) = 14 sq. units.

Together this makes the surface area of the prism 14+48 = 62 sq. units.
