Demarcus has to wrap a gift for his friend's birthday party. The gift is in a rectangular box with the dimensions shown below. H
pochemuha

The surface area of the box is <u>1048 square inches</u>

<h3>How to calculate the total surface area of the box</h3>

The formula for calculating the surface area of the prism is expressed as:

Surface area = 2(lw + wh +lh)

Given the following

l = 20in

w = 8in

h = 13in

Substitute the given parameters'

Surface area = 2(lw + wh +lh)

Surface area = 2(20(8) + 8(13) +20(13))

Surface area = 2(160+104+260)

Surface area = 1048 square inches

Hence surface area of the box is <u>1048 square inches</u>

The center of a circle is located at (2, 3) and has a radius of 6 units. Which equation represents this circle?
Helen [10]

By using the general equation for a circle, we will see that the correct option is:

(x - 2)^2 + (y - 3)^2 = 36

<h3>How to find the equation for a circle?</h3>

The general equation for a circle centered at the point (a, b) of radius R is given by:

(x - a)^2 + (y - b)^2 = R^2

In this case, the center is (2, 3) and the radius is R = 6 units, replacing that in the above equation we get:

(x - 2)^2 + (y - 3)^2 = 6^2

(x - 2)^2 + (y - 3)^2 = 36

So the correct option is B.

prisoha [69]
First, we must convert the feet to inches so they have the same units.

1ft: 12 in
3(12)3 :36 inches
2(12 = 24 inches

So Nicole's poster is 36in to 24in
Her friends mini poster is 2 in to 1 1/3 in
36 divided by 2 is 18, and 24 divided by 1 1/3 also equals 18

So the scale factor is 18:1
