Answer: 80 cubic centimeters

Step-by-step explanation:

Use the formula: V= $\frac{1}{3}$ Bh

(B is the area of the pyramid's base)

V= $\frac{1}{3}$ (16)(15)

Multiply: 16 x 15 =240

$\frac{1\\}{3}$ x 240 = 80

V= 80cubic centimeters

Anyone know the answer?

To solve your question, you add all of the measurements together, set them equal to 180, solve for x, and plug x back in for whichever angle they are asking for; in this case, they want angle R

7x + 12x + 20 + 20x - 35 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 5

Angle R = 12x + 20
12(5) + 20
60 + 20
80

Option C is your answer.
