Volume and Surface Area Review

Front

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

Back

The total surface area (SA) of a prism can be calculated using the formula: SA = 2B + Ph, where B is the area of the base, P is the perimeter of the base, and h is the height of the prism.

Front

How do you calculate the volume of a prism?

Back

The volume (V) of a prism is calculated using the formula: V = B * h, where B is the area of the base and h is the height of the prism.

What is the formula for the volume of a cylinder?

Back

The volume (V) of a cylinder is given by the formula: V = πr²h, where r is the radius of the base and h is the height of the cylinder.

Front

How do you find the height of a cylinder given its volume and diameter?

Back

To find the height (h) of a cylinder, use the formula: h = V / (πr²), where V is the volume and r is the radius (which is half of the diameter).

Front

What is the relationship between diameter and radius?

Back

The radius (r) is half of the diameter (d). Therefore, r = d/2.

Front

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

Back

The surface area (SA) of a cylinder is calculated using the formula: SA = 2πr² + 2πrh, where r is the radius and h is the height.

Front

What is a composite figure?

Back

A composite figure is a shape that is made up of two or more simple geometric shapes, such as rectangles, triangles, and circles.

Front

How do you calculate the volume of a composite figure?

Back

To calculate the volume of a composite figure, find the volume of each individual shape and then sum them up.

Front

What units are used to measure volume?

Back

Volume is typically measured in cubic units, such as cubic inches (in³), cubic feet (ft³), or cubic meters (m³).

Front

What is the significance of rounding in volume calculations?

Back

Rounding is important in volume calculations to provide a practical answer that is easy to interpret, especially when measurements are not exact.
