Unit One Review: Area & Surface Area

Front

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

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the surface area of a cube with edge length 2 cm?

Back

Surface Area = 6 * (2 cm)^2 = 24 cm².

Front

What is a triangular prism?

Back

A 3-dimensional shape with two triangular bases and three rectangular faces.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the area of a rectangle with length 5 m and width 3 m?

Back

Area = length * width = 5 m * 3 m = 15 m².

Front

What is the formula for the area of a trapezoid?

Back

Area = 1/2 * (base1 + base2) * height.

Front

What is the area of a parallelogram with base 8 m and height 5 m?

Back

Area = base * height = 8 m * 5 m = 40 m².

Front

What does 5³ mean?

Back

5³ = 5 x 5 x 5 = 125.

Front

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

Back

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

Front

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

Back

Surface Area = 4πr², where r = radius.
