Question

Please Help - Find the Volume

Answer 1

Answer:

1,982 ft³

Step-by-step explanation:

Solving

Volume of rectangular prism (below)

• lbh
• 12 x 12 x 12
• 144 x 12
• 1728 ft³

Volume of square pyramid

• 1/3Bh
• 1/3 x 144 x √28
• 48 x 5.29
• 253.92

Total Volume : 1728 + 253.92 = 1,981.92 ft³ ≅ 1,982 ft³

Answer 2

Answer:

1982  ft^3    ( rounded)

Step-by-step explanation:

The cube bottom is   12 x 12 x 12  = 1728

The pyramid top is  1/3 ( 12*12) * sqrt 28 = 253.99

added together = ~ 1982  

( you have to use the HEIGHT of the pyramid for the volume calculation      V = 1/3 *  base area * height        height = sqrt (28)  )
