Question

Bethany is building a storage trunk. 5ft long, 4ft height and 2ft wide. how much wood is needed to make the trunk

Answer 1

76 square feet of wood.

Step-by-step explanation:

Bethany is building a storage trunk with the following dimensions:

• Length = 5 ft.

,

• Height = 4 ft.

,

• Width = 2 ft.

We are to determine how much wood is needed to make the trunk.

The amount of wood that will be needed to make the truck is the surface area of the trunk. The storage trunk is in the shape of a rectangular prism.

The surface area of a rectangular prism is found using the formula below:

`\text{Surface Area=2(LW+LH+WH)}`

Substitute the given dimensions:

`\begin{gathered} \text{Surface Area}=2(5*2+5*4+2*4) \\ =2(10+20+8) \\ =2*38 \\ =76\; ft^2 \end{gathered}`

Bethany needs 76 square feet of wood to make the trunk.
