What is surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies. It is measured in square units.

Front

How do you calculate the surface area of a rectangular prism?

Back

To calculate the surface area of a rectangular prism, use the formula: Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is the surface area of a rectangular prism with length 5 cm, width 3 cm, and height 4 cm?

Back

Surface Area = 2(5*3 + 5*4 + 3*4) = 2(15 + 20 + 12) = 2(47) = 94 cm².

Front

What units are used to measure surface area?

Back

Surface area is measured in square units, such as cm², m², or ft².

Front

What is the surface area of a cube with side length 6 cm?

Back

Surface Area = 6 * (side length)² = 6 * (6 cm)² = 6 * 36 cm² = 216 cm².

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional shape that can be folded to form the shape.

Front

How do you find the surface area using a net?

Back

To find the surface area using a net, calculate the area of each face of the net and then sum those areas.

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) = 2π(3)(8) = 48π cm².

Front

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

Back

The formula for the surface area of a sphere is Surface Area = 4πr², where r is the radius.

Front

What is the surface area of a sphere with a radius of 4 cm?

Back

Surface Area = 4π(4 cm)² = 4π(16 cm²) = 64π cm².
