To find the volume of a right rectangular prism, you can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
In this case, the dimensions given are:
- Length = 4
- Width = 0.7
- Height = 1.5
Now plug these values into the formula:
\[ \text{Volume} = 4 \times 0.7 \times 1.5 \]
First, calculate \( 4 \times 0.7 \):
\[ 4 \times 0.7 = 2.8 \]
Next, multiply the result by 1.5:
\[ 2.8 \times 1.5 = 4.2 \]
Thus, the volume of the right rectangular prism is
\[ \text{Volume} = 4.2 \]
So, the answer in decimal form is 4.2.
