We have been given that each pant's leg has an opening with a circumference of 8.5 inches. It took 15 stitches to make 3 inches in width. We are asked to find the number of stitches required to make up the circumference.

Let us find stitches needed to make 1 inch by dividing 15 by 3.

$\text{Stitches needed to make 1 inch}=\frac{15}{3}$

$\text{Stitches needed to make 1 inch}=5$

Since 5 stitches make 1 inch, so to find stitches needed to make 8.5 inches, we will multiply 8.5 by 5 as:

$\text{Stitches needed to make 8.5 inches}=5\times 8.5$

$\text{Stitches needed to make 8.5 inches}=42.5$

Upon rounding to nearest stitch, we will get:

$\text{Stitches needed to make 8.5 inches}\approx 43$

Therefore, 43 stitches will make up the circumference.

What expressions represent the surface area of a cube with an edge length of 7 units

Aneli [31]

Surface area of a cube: 6 ( edge lenght )^2

A cube has 6 square faces, so we have to multiply the area of each face by 6.

Replacing:

SA = 6 (7)^2 = 6 (49) =294 squared units
