Been trying to figure it out for a while and when you answer tell me how to do it and explain

To find the amount of cardboard needed, we need to find the surface area of the box. We can do this by finding the area of each shape in the net.

All of the shapes are rectangles, the formula for the area of the rectangle is A = w*l

There are 4 similar shapes that are 4 by 6. The area of each of these shapes is 24 ft^2.

There are 2 similar shapes tht are 4 by 4. The area of each of these shapes is 16 ft^2.

Now, we need to add these areas together.

24(4) + 16(2) = SA

96 + 32 = SA

128 = SA

So, he'll need 128 ft^2 of cardboard to create the box.

Hey There,

The answer would be 128ft.

Calculate the area of each individual face and add it up in order to find the surface area.

Rectangle

6*4= 24

24 * 4 = 96

The area of each individual rectangle added together is 96 ft.

Square

4 * 4= 16

16*2= 32

The area of each individual square added together is 32 ft.

Add these two numbers together.

96 + 32 = 128

Therefore, the answer would be 128ft.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

the answer is 2/54
