Question

Can you help me with this 1 1/2 4 2 1/2 use the volume formula to find the volume of this prism

Answer 1

To calculate the volume of this rectangular prism we use the formula:

`V=l* w* h`

Where V is volume, l is length, w is width and h is height.

Step 1. Identify the length, width, and height.

The values are shown in the following image:

`\begin{gathered} l=4 \\ w=1(1)/(2) \\ h=2(1)/(2) \end{gathered}`

Step 2. Convert the mixed numbers to a decimal:

`\begin{gathered} w=1(1)/(2) \\ w=1.5 \end{gathered}`

And

`\begin{gathered} h=2(1)/(2) \\ h=2.5 \end{gathered}`

Step 3. Substitute the values of l, w, and h into the volume formula:

`V=4*1.5*2.5`

Solving the operations we find the answer in cubic units:

`V=15`

Answer: B. 15 cubic units
