Answer:

2: The perimeter of the base is 37 units.

Step-by-step explanation:

1. A = LW = 21 * 16 = 336 units^2 True

2. P = 2(L + W) = 2(21 + 16) = 2(37) = 74 units False

3. H = 21 units True

4. SA = 2LW + 2H(L + W) = 2(21)(16) + 2(21)(21 + 16) = 2226 units^2 True

What is the square feet of 71inces x 36inches?

Setler [38]

71 inches X 36 inches = 2556 sq inches

convert sq.feet to sq.inches.

12 sq. feet = 1 sq. inch

2556 sq. feet × 1 sq. inch ÷ 12 sq. feet = 213 sq. inches (sq. feet ÷ sq. feet cancels out the feet variable leaving sq. inch)

Find the height of a square pyramid that has a volume of 84 cubic feet and a base length of 6 feet v=1/3b(2)h

Serga [27]

Answer:

<h3>The height of the pyramid is 7 feet</h3>

Step-by-step explanation:

Let h represent the height of the pyramid

Volume of a pyramid is given by

$V = \frac{1}{3} \times area \: of \: base \: \times height$

Volume of pyramid = 84ft³

To find the height of the pyramid we must first find the area of the base

Since it's a square pyramid it's base is a square

Area of a square = l²

where l is the length of one side

l = 6feet

Area = 6² = 36ft²

So we have

$84 = \frac{1}{3} \times 36 \times h$

84 = 12h

Divide both sides by 12

The height of the pyramid is 7 feet

Hope this helps you
