Answer:

A

Step-by-step explanation:

For the first block, you need to multiply a x a x b

3 x 3 x 6 = 54

For the 2nd block, you need to multiply a x a x c

3 x 3 x 12 = 108

Now you need to add both volumes of the blocks

108 + 54 = 162 in^3

Alenkinab [10]

Answer:

Area of trapezoid is 16ft^2.

Therefore, option 2nd  is correct.

Step-by-step explanation:

We have been given both the sides a=3 and b=5.

And height that is h=4

We will use the formula find the area of trapezoid is:

\frac{a+b}{2}\cdot h

Substitute the formula we get:

\frac{3+5}{2}\cdot 4

\Rightarrow \frac{8}{2}\cdot 4

\Rightarrow 16.

Area of trapezoid is 16ft^2.

Therefore, option 2nd  is correct.
