Answer 1

Wrong

Answer 2

To find the surface area of a triangular prism, we first need to calculate the areas of all the surfaces and then add them together.

Surface area of the triangular bases:
Area = (1/2) * base * height
Area = (1/2) * 4 * 3 = 6
Area = (1/2) * 5 * 3 = 7.5

Surface area of the three rectangular faces:
Area = base * height
Area = 4 * 4 = 16
Area = 5 * 4 = 20
Area = 5 * 4 = 20

Total surface area:
6 (two triangular bases) + 16 + 20 + 20 = 62

Therefore, the surface area of the triangular prism is 62 square units.

Answer 3

Apologies for the mistake in my previous calculation. Let's correct it:

To find the surface area of a triangular prism, we need to calculate the areas of all the surfaces and then add them together.

Surface area of the triangular bases:
Area = (1/2) * base * height
Area = (1/2) * 4 * 4 = 8
Area = (1/2) * 5 * 3 = 7.5

Surface area of the three rectangular faces:
Area = base * height
Area = 4 * 4 = 16
Area = 5 * 4 = 20
Area = 5 * 4 = 20

Total surface area:
8 (two triangular bases) + 16 + 20 + 20 = 64

Therefore, the surface area of the triangular prism is 64 square units.
