Lets write this out:-
20 ÷ 2 × (5+5).
To answer this we will use the Oder Of operations.
PEMDAS.
Since there is parenthesis, we will 1st solve that.
20 ÷ 2 × (5 + 5)
20 ÷ 2 × (10)
Next we will do division.
10 × (10).
Finally multiply.
100.
So, 20 ÷ 2 × (5 + 5) = 100.

The surface area of the prism is given by:
Area=2(x*2x)+2(x(x+3))+2(2x(x+3))
=4x^2+2x^2+6x+4x^2+12x
=10x^2+18x sq. units
The volume will be given by:
V=length*width*height
=2x*x*(x+3)
=2x^3+6x^2 cubic units
