Volume of a Rectangular Prism = Length * Width * Height
Step 1:
Double your dimensions
5 cm x 2 = 10 cm
3 cm x 2 = 6 cm
4 cm x 2 = 8 cm
Step 2:
Multiply them together
Volume = 10 x 6 x 8
Volume = 60 * 8
Volume = 480 cm^3

There are 6 squares so u multiply 6x3=18 is the total surface area
Your answer is 3x^(2)+3x+6
Hope this helped!
