Jeremy made one vertical stack of boxes that had a surface area of 17,052 square centimeters. How many shoe boxes were in the stack?

there are 7 boxes in the stack.

Step-by-step explanation:

After a quick online search, I've found that the dimensions of each box are:

Height = H = 18cm

Length = L = 40cm

Width = W = 21cm

If we stack the boxes, then the only thing that changes in the figure is the height, so if we stack N boxes, the dimensions will be:

Height = H = N*18cm

Length = L = 40cm

Width = W = 21cm

And for a rectangular prism of height H, width W, and length L, the surface is:

S = 2*(H*W + W*L + H*L)

Then for our stack of boxes, the surface is:

S = 2*(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm)

And we know that the total surface is 17,052 cm^2

Then we just need to solve:

2*(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = 17,052 cm^2

(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = (17,052 cm^2)/2

(40cm*21cm + 40cm*N*18cm + 21cm*N*18cm) = 8,526 cm^2

840 cm^2 + N*720 cm^2 + N*378 cm^2 = 8,526 cm^2

N*(720 cm^2 + 378 cm^2) =  8,526 cm^2 - 840 cm^2 = 7,686 cm^2

N*(1,098 cm^2) = 7,686 cm^2

N = (7,686 cm^2)/(1,098 cm^2) = 7

So there are 7 boxes in the stack.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
