Surface Area

Front

Lateral Surface Area is...

Back

Only the area of the sides of a figure.

Front

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

Back

Lateral Surface Area = 2h(l + w), where h is height, l is length, and w is width.

Front

What is the lateral surface area of a rectangular prism with height 10 cm, length 5 cm, and width 4 cm?

Back

Lateral Surface Area = 2(10)(5 + 4) = 180 cm².

Front

What is the formula for the surface area of a square pyramid?

Back

Surface Area = Base Area + Lateral Area = s² + 2sl, where s is the side length of the base and l is the slant height.

Front

Calculate the surface area of a square pyramid with base side 6 cm and slant height 5 cm.

Back

Surface Area = 6² + 2(6)(5) = 36 + 60 = 96 cm².

Front

What is the formula for the composite surface area of two shapes combined?

Back

Composite Surface Area = Surface Area of Shape 1 + Surface Area of Shape 2 - Area of Overlap.

Front

Calculate the composite surface area of a square prism with base side 4 cm and height 10 cm.

Back

Surface Area = 6(4²) + 4(4)(10) = 96 + 160 = 256 cm².

Front

What is the surface area of a cylinder with radius 3 cm and height 7 cm?

Back

Surface Area = 2πr(h + r) = 2π(3)(7 + 3) = 60π cm².

Front

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

Back

Surface Area = 4πr², where r is the radius.

Front

Calculate the surface area of a sphere with a radius of 5 cm.

Back

Surface Area = 4π(5)² = 100π cm².
