The base edge of a square pyramid is 30 cm. the pyramid is 6 cm tall. find the volume of the pyramid

5400 cm^3

Step-by-step explanation:

Volume = Base Area * H

Base area is the area of a square with one side = 30 cm

H = 6cm

Base Area = s^2

Base Area = 30^2 = 900

Volume  =  900 * 6

Volume = 5400 cm^3

1800 cm³

Step-by-step explanation:

Recall that the formula for the area of a square is A = s², where s is the side length.

Here, that area is A = (30 cm)²2.

The formula for the volume of a square pyramid is:

V = (1/3)(base area)(height)

   = (1/3)(30 cm)²2*(6 cm)

   = (1/3)(900 cm²)(6 cm) = 1800 cm³

The volume of this pyramid is 1800 cm³.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
