Surface Area of Shapes Made of Cubes — Easy Worksheet 1

Grade 6 · MathSheets    Name: ____________________   Date: __________

Each small cube is 1 unit on a side. Count every outside square face, including the ones you cannot see (bottom, back and left). There are no hidden holes.

How to solve

Surface area is the number of outside squares. Look from all six directions: top, bottom, front, back, left and right, and count the squares you would see from each. Top and bottom match, front and back match, and left and right match, so (top + front + right) × 2 works for boxes and staircases. A row of 3 cubes: top 3, front 3, right 1 → (3 + 3 + 1) × 2 = 14 square units.

Example

Each cube is 1 in on a side. Find the surface area of the solid in square inches.

Answer: 10
