To easily find out the surface area and volume of cubes and rectangular prisms, remember these simple formulas:

Cube:

• Surface Area:

  • The formula is:
    $SA = 6a^2$
    Here, $a$ stands for the length of one side of the cube.

• Volume:

  • The formula is:
    $V = a^3$
    This means you multiply the side length by itself three times.

Rectangular Prism:

• Surface Area:

  • The formula is:
    $SA = 2(lw + lh + wh)$
    In this formula, $l$ is the length, $w$ is the width, and $h$ is the height.

• Volume:

  • The formula is:
    $V = lwh$
    Here, you just multiply the length, width, and height together.

These formulas will help you quickly find the surface area and volume for both shapes!
