Find the total area of a cuboid having a square shaped base and a volume of

- A
- B
- C
- D

### Example

Find the total area of a cuboid having a square shaped base and a volume of

### Solution

Step 1: Find the area of the cuboid's base.

Use the formula for the volume of a cuboid, and solve for the area of the base

Step 2: Find the side length of the square base.

Use the formula for the area of a square, and solve for the side length

Note that we only use the positive value when taking the square root below, because it does not make sense to have a side length with a negative value.

Step 3: Find the lateral area of the cuboid.

Step 4: Find the total area of the cuboid.
