Surface area of prisms

Front

What does 'P' stand for in the surface area formulas?

Back

Perimeter of the Base

Front

In the equation: Ph + 2B, what does the B stand for?

Back

Area of Base

Front

What is the formula for the surface area of a prism?

Back

Surface Area = Ph + 2B (where P = perimeter of the base, h = height, B = area of the base)

Front

What is the total surface area of a rectangular prism with dimensions 4m x 3m x 5m?

Back

94 m²

Front

How do you calculate the area of a triangle?

Back

Area = 1/2 * base * height

Front

What is the surface area of a triangular prism with a base area of 20 cm² and a height of 10 cm?

Back

Surface Area = Ph + 2B = (Perimeter of base * height) + 2 * base area

Front

What is the perimeter of a base that is a rectangle with lengths 5m and 3m?

Back

Perimeter = 2 * (length + width) = 2 * (5 + 3) = 16 m

Front

If the base of a prism is a triangle with sides 3 cm, 4 cm, and 5 cm, what is the perimeter?

Back

Perimeter = 3 + 4 + 5 = 12 cm

Front

What is the surface area of a cylinder with a radius of 3 cm and a height of 5 cm?

Back

Surface Area = 2πr(h + r) = 2π(3)(5 + 3) = 48π cm²

Front

What is the difference between lateral surface area and total surface area?

Back

Lateral surface area is the area of the sides only, while total surface area includes the area of the bases.
