To find volume, you calculate the area of the base and then times the height of the figure to give it 3 dimensions. Find the area of the base of this figure ( $A=lw$ ).

• 40 $in^2$   

• 30 $in^2$  

• 12 $in^2$  

• 17 $in^2$  

You found the area of the base to be 30 $in^2$ , you will multiply that area by the height of the figure to find the total volume. What is the volume of this figure?

• 160 $in^2$

• 30 $in^2$

• 120 $in^2$

• 17 $in^2$
