Question

FIND THE TOTAL SURFACE AREA OF THE OBJECT

Answer 1

A=2(l*b+l*h+b*h)

Answer 2

Yes, to find the Surface Area of a rectangular Prism you must use this formula : \(\rm SA~=~2(l\times w~+~l\times h~+~w\times h)\)

l = 5
w = 6
h = 2

If you plug in all the information into the formula, you will have this :
\(\rm SA~=~2(5\times 6~+~5\times 2~+~6\times 2)\)

First you must do what is in the parenthesis. Following the order of operations, you do what is in the parenthesis and then we multiply/divide and then add/subtract.

Step 1 :
Multiply/Divide
All we see here is multiplication and no division, so therefore, we multiply starting from the left of the equation and ending at the right.
The first section of multiplication we see is \(6\times 5\), so can you tell me what is \(6\times 5\)?
