Surface Area and Volume of Prisms

Front

What is surface area?

Back

The sum of the areas of all the surfaces (faces) of a 3D shape.

Front

What is volume?

Back

The amount of space occupied by a 3D shape, measured in cubic units.

Front

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

Back

Add the areas of all six faces: SA = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

What is a prism?

Back

A solid shape with two identical ends and flat sides.

Front

What is the formula for the volume of a triangular prism?

Back

Volume = (Base Area × Height) of the prism.

Front

What units are used for surface area?

Back

Square units (e.g., cm², m², in²).

Front

What units are used for volume?

Back

Cubic units (e.g., cm³, m³, ft³).

Front

If a rectangular prism has a length of 4 cm, width of 3 cm, and height of 5 cm, what is its volume?

Back

60 cm³.

Front

If a rectangular prism has a length of 2 m, width of 3 m, and height of 4 m, what is its surface area?

Back

2(2*3 + 2*4 + 3*4) = 2(6 + 8 + 12) = 52 m².
