Find the volume of a pyramid with a square base, where the perimeter of the base is
Liula [17]

Answer:

  33.4 m^3

Step-by-step explanation:

The edge length of the base is 1/4 of the perimeter, so is ...

  (10.3 m)/4 = 2.575 m

Then the area of the base is the square of this, or ...

  B = (2.575 m)^2 = 6.630625 m^2

The volume is ...

  V = (1/3)Bh = (1/3)(6.630625 m^2)(15.1 m) ≈ 33.4 m^3

The volume of the pyramid is about 33.4 cubic meters.

The base is a right triangle with a leg of 12 in. and hypotenuse of 15 in.
EastWind [94]

Answer:

V = 540 inches ^3

Step-by-step explanation:

The area of the base is found be finding the other leg

a^2 +b^2 = c^2

12^2+b^2 = 15^2

144 +b^2 = 225

b^2 = 225-144

b^2=81

Take the square root of each side

b = 9

We can find the area of the triangle

B = 1/2 (9*12)

B =54

The Volume is given by

V = Bh

V = 54*10

V = 540 inches ^3
