Volume is the easiest to solve. Simply multiply height by width by length (v=l•w•h)
We will plug in the values to get (v=2cm•2cm•3cm) —> (v=12cm cubed, written as 12cm^3)
Next we will find the surface area. The surface area is found with the sum of area of all of the sides.
Think of it as if the box was a hollow box, and you took apart each side and laid them flat.
2 sides of the rectangle will by 2cm by 2cm,
and 4 sides of the rectangle will by 2cm by 3cm.
2 sides • 2cm by 2cm = 8cm
4 sides • 2cm by 3cm = 24cm
8cm + 24cm = 32cm^2 total surface area
Answers:
V=12cm^3
SA=32cm^2
