Cubes and rectangular prisms are important shapes in geometry.

1. Cubes:

• Surface Area (SA): To find the surface area, we use the formula: SA = 6s² Here, s is the length of one side.

  For example, if the side length is 4, we calculate:

  SA = 6 × 4² = 96 square units.

• Volume (V): The formula for volume is: V = s³.

  For our cube with a side of 4, we find:

  V = 4³ = 64 cubic units.

2. Rectangular Prisms:

• Surface Area (SA): To find the surface area, we use: SA = 2lw + 2lh + 2wh.

  Here, l is length, w is width, and h is height.

  For a prism with l = 3, w = 2, and h = 5, we calculate:

  SA = 2(3 × 2 + 3 × 5 + 2 × 5) = 62 square units.

• Volume (V): The formula for volume is: V = lwh.

  For the same prism, we find:

  V = 3 × 2 × 5 = 30 cubic units.

Knowing how to calculate surface area and volume is useful in many areas, like building things or making products.
