Question

How do i find this out

Answer 1

Answer:

The volume is 4908.75 ft³.

Step-by-step explanation:

Don't think about it as a block. Remember the rule for volumes of prisms: cross sectional area times length.

In this case, the cross section is a trapezium, so let's find the area for it:

$a = \frac{13.1 + 25.4}{2} \times 17 \\ a = 19.25 \times 17 \\ a = 327.25$

Now, multiply it by the length to get the volume:

$v = 327.25 \times 15 \\ v = 4908.75$
