The formula to solve for thee area of a square pyramid is [ V = 1/3 * b² * h ]

b² = base area (b = length of one side of the base)

h = height

The only option that as a base length of 12cm. and a height of 14cm. is the first option.

Solve for the volume if needed.

V = 1/3(12²)(14)

V = 1/3(144)(14)

V = 1/3(2,016)

V = 672cm²

Best of Luck!

Answer:

First one

Step-by-step explanation:

⅓ × base area × height

Base area = 12²

So each side of the base is 12

Height is 14

Answer:

342 inches, or 28.5 feet, or 9.5 yards

Step-by-step explanation:

It is perhaps easiest to start with all the dimensions in inches.

13.5 ft = (13.5 ft)(12 in/ft) = 162 in

3.5 yd = (3.5 yd)(36 in/yd) = 126 in

Then the total of the lengths of ribbon is ...

54 in + 162 in + 126 in = 342 in

Converting to feet, we get ...

(342 in)/(12 in/ft) = 28.5 ft

And converting to yards, we get ...

(342 in)/(36 in/yd) = 9.5 yd

The total length of ribbon is 342 inches, or 28.5 feet, or 9.5 yards.

Answer:

see explanation

Step-by-step explanation:

The area of a rectangle = length × width

To find the width, divide the area by the length

width = $\frac{area}{length}$ = $\frac{3x^2+9x}{3x}$

To simplify divide each term on the numerator by 3x

= $\frac{3x^2}{3x}$ + $\frac{9x}{3x}$ = x + 3 ← width
