Find the volume of a square pyramid if the area of the base is 441 ft² and the height is 24 ft. Round to the nearest tenth.

Volume = _____ ft³


Sagot :

Certainly! Let's break down the problem step-by-step to find the volume of a square pyramid with a given base area and height:

1. Identify the given values:
- The area of the base ([tex]\(A\)[/tex]) of the square pyramid is 441 square feet.
- The height ([tex]\(h\)[/tex]) of the pyramid is 24 feet.

2. Recall the formula for the volume of a square pyramid:
[tex]\[ \text{Volume} = \frac{1}{3} \times (\text{Base Area}) \times (\text{Height}) \][/tex]
Here, substituting the given values:
[tex]\[ \text{Volume} = \frac{1}{3} \times 441 \text{ ft}^2 \times 24 \text{ ft} \][/tex]

3. Calculate the volume:
[tex]\[ \text{Volume} = \frac{1}{3} \times 441 \times 24 \][/tex]

4. Break it down further:
[tex]\[ 441 \times 24 = 10584 \][/tex]
[tex]\[ \frac{1}{3} \times 10584 = 3528 \text{ ft}^3 \][/tex]

5. Round the volume to the nearest tenth:
- The volume, calculated as [tex]\(3528\)[/tex] cubic feet, is already a whole number.
- Thus, when rounded to the nearest tenth, it remains [tex]\(3528.0\)[/tex] cubic feet.

Therefore, the volume of the square pyramid, rounded to the nearest tenth, is [tex]\(3528.0\)[/tex] cubic feet.
