Find the lateral surface area of the rectangular prism represented by the given net

12 cm
7 cm
3 cm

1 answer

The lateral surface area of a rectangular prism is calculated by finding the perimeter of the base and multiplying it by the height.

In this case, the dimensions of the base of the rectangular prism are 12 cm and 7 cm.

Perimeter of the base = 2(12 cm) + 2(7 cm) = 24 cm + 14 cm = 38 cm

The height of the prism is 3 cm.

Lateral surface area = Perimeter of base * height
Lateral surface area = 38 cm * 3 cm
Lateral surface area = 114 cm²

Therefore, the lateral surface area of the rectangular prism is 114 cm².
