The perimeter of the base of a square pyramid is 16 feet and it stands 20 ft tall. Calculate the volume.​
Vikentia [17]

Answer: 1706.67 feet

Step-by-step explanation:

Formula: Volume = \frac{1}{3} \alpha^{2}h

a is the length of the base's edge and h is the height. Since 16 is the length we would square it as it is the length, then we would multiply it by the height which is 20 ft.

<u>Steps: Multiply</u>

Volume = \frac{1}{3} \alpha^{2}h

= \frac{1}{3} * 16^{2} * 20

= 1706.67 feet

~I hope I helped you :)~

scZoUnD [109]

Answer:

63 and 72

Step-by-step explanation:

Sum the parts of the ratio, 7 + 8 = 15 parts

Divide the sum by 15 to find the value of one part of the ratio

135 ÷ 15 = 9 ← value of 1 part of the ratio, thus

7 parts = 7 × 9 = 63

8 parts = 8 × 9 = 72

The numbers are 63 and 72
