A company makes storage containers with sheet steel walls. The containers are shaped like rectangular prisms, as shown below. If the company is going to make 10 containers, how many square meters of sheet steel will be needed

of sheet steel are needed

Step-by-step explanation:

Given

The missing dimensions are:

--- number of containers

Required

The surface area of all containers

First, we calculate the surface area (A) of 1 container

The surface area of 10 is:

3

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!
