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.

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

Back

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

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

Back

The surface area of a cylinder is given by the formula: SA = 2πr(h + r), where r is the radius and h is the height.

What does 'lateral surface area' mean?

Back

Lateral surface area refers to the area of the sides of a three-dimensional object, excluding the top and bottom surfaces.

Front

How do you calculate 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.

How do you round numbers to the nearest tenth?

Back

To round to the nearest tenth, look at the hundredths place. If it's 5 or more, round up; if it's less than 5, round down.

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

Back

Total surface area = 2πr(h + r) = 2 * 3.14 * 3(5 + 3) = 150.72 m².
