SURFACE AREA OF RECTANGULAR PRISMS

Front

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

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

How many faces does a rectangular prism have?

Back

A rectangular prism has 6 faces.

Front

What is the unit of measurement for surface area?

Back

The unit of measurement for surface area is square units (e.g., square inches, square centimeters).

Front

If the length of a rectangular prism is 5 inches, width is 4 inches, and height is 3 inches, what is its surface area?

Back

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

Front

What does 'total surface area' mean?

Back

Total surface area is the sum of the areas of all the faces of a three-dimensional shape.

Front

If a rectangular prism has a surface area of 88 square inches, what could be its dimensions?

Back

Possible dimensions could be 4 in. x 4 in. x 3 in. (or other combinations that satisfy the surface area formula).

Front

What is the relationship between the dimensions of a rectangular prism and its surface area?

Back

The surface area increases as the dimensions (length, width, height) increase.

Front

What is the surface area of a rectangular prism with dimensions 2 cm, 3 cm, and 4 cm?

Back

Surface Area = 2(2*3 + 2*4 + 3*4) = 2(6 + 8 + 12) = 2(26) = 52 cm².

Front

Can the surface area of a rectangular prism be the same for different dimensions?

Back

Yes, different sets of dimensions can yield the same surface area.

Front

What is the surface area of a cube with a side length of 3 inches?

Back

Surface Area = 6 * (side length)² = 6 * (3)² = 6 * 9 = 54 square inches.
