The area of the base of a prism is 50 mm2. The perimeter of the base is 30 mm. The height of the prism is 7 mm. What is the surface area of the prism? mm2
Given: Base of the prism: 50 mm² Perimeter of base: 30 mm Height of prism: 7 mm
The formula of the surface area of a prism is S.A = 2 × Area of base + Perimeter of base × Height of prism Plug in the given S.A = 2 × 50 + 30 × 7 = 100 + 210 = 310 mm²
