A square pyramid with a height of 7 inches has volume of 47.25 cubic inches. Find the side length of the square base

Respuesta :

Hello,
Volume of the square pyramid=
1/3×B×h where B represent Base and h represent height

Now, substitute the information that we had from this problem into the formula.
47.25=1/3×B×7
Times 3 from both side
141.75=7B
Divide B from both side
B=20.25 square inches
B=s^2
Square root it to get
s=4.5 inches. As a result, the side length of square base is 4.5 inches. Hope it help!

The side length of the square base is 4.5.

What is a square pyramid?

'A square pyramid is a three-dimensional geometric shape that has a square base and four triangular sides that are joined at a vertex.'

According to the given problem,

Let the side length of the square base be a,

We know,

Volume  =  [tex]\frac{1}{3}a^{2}h[/tex]

⇒ 47.25 =  [tex]\frac{1}{3}a^{2}h[/tex]

⇒ 47.25 × 3 = a²h

⇒ 141.75 = a²h

⇒ 141.75/7 = a²

⇒ a² = 20.25

⇒ a = 4.5

Hence, we can conclude, the side length of the square base is 4.5 inches.
