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

Back

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

Front

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

Back

To find the surface area of a triangular prism, use the formula: SA = bh + (p * h), where b is the base area of the triangle, p is the perimeter of the triangle's base, and h is the height of the prism.

Front

What is the surface area formula for a square pyramid?

Back

The surface area (SA) of a square pyramid is calculated using the formula: SA = b^2 + 2 * (b * l), where b is the length of the base and l is the slant height.

Front

What is the total surface area of a cylinder?

Back

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

Front

What is the difference between lateral surface area and total surface area?

Back

Lateral surface area refers to the area of the sides of a 3D shape, excluding the bases, while total surface area includes the area of the bases as well.

Front

How do you calculate the surface area of a cone?

Back

The surface area (SA) of a cone is calculated using the formula: SA = πr(l + r), where r is the radius of the base and l is the slant height.

Front

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

Back

The surface area (SA) of a sphere is calculated using the formula: SA = 4πr^2, where r is the radius of the sphere.

Front

What is the significance of units in surface area calculations?

Back

Units in surface area calculations are important because they indicate the measurement of area, typically expressed in square units (e.g., square meters, square centimeters).

Front

How do you find the surface area of a composite shape?

Back

To find the surface area of a composite shape, calculate the surface area of each individual shape and then sum them up, ensuring to account for any overlapping areas.

Front

What is the surface area of a cube?

Back

The surface area (SA) of a cube is calculated using the formula: SA = 6a^2, where a is the length of one side of the cube.
