Question 912425: The question is=
What will be the total surface area of a cardboard box whose one side is missing which is the top ,whose LENGTH=6cm,
BREATH=4cm and HEIGHT=5cm
So here I'm confused that if we have to find the TOTAL SURFACE AREA of the cardboard box whose top side is missing then we should include the value its top side in the surface area or not.
Although, they are asking the total surface area but its top side is missing.

You can put this solution on YOUR website!
Total surface area of the box without a top.
Look at the surface area of each part.
Bottom : A%5Bb%5D=L%2AW
Long Sides : A%5Bls%5D=2%2AL%2AH Multiplier of 2 since there are two long sides.
Short Sides : A%5Bss%5D=2%2AW%2AH Again 2 since there are two short sides.
Top : A%5Bt%5D=0 There is no top.
So then add it together,
A=L%2AW%2B2%2AL%2AH%2B2%2AW%2AH
Breath is W. I usually use width.
A=6%2A4%2B2%2A6%2A5%2B2%2A4%2A5
A=24%2B60%2B40
A=124cm%5E2
