When given a rectangular prism whose length measures 3 cm and height measures 4 cm on 4 sides. The 2 remaining faces on each end are squares whose sides all measure 2cm.
Find the surface area.
What is 4 x 3 = 12 x 4= 48 square centimeters (because this is for 4 faces of the figure)
2 x 2= 4x 2= 8 (because of the 2 square faces on each end)
Then add 48 +8= 56 square centimeters
