You're asked to
find the surface area of each cube.
---
✔ Key Concept:
A
cube has
6 identical square faces.
The formula for the
surface area (SA) of a cube is:
>
SA = 6 × (side length)²
or
>
SA = 6s², where
s is the length of one edge.
---
We’ll calculate the surface area for each cube using this formula.

🔢 Solutions:
#### 1) Side = 22 cm
SA = 6 × (22)² = 6 × 484 =
2,904 cm²
#### 2) Side = 16 mm
SA = 6 × (16)² = 6 × 256 =
1,536 mm²
#### 3) Side = 9 in
SA = 6 × (9)² = 6 × 81 =
486 in²
#### 4) Side = 5 m
SA = 6 × (5)² = 6 × 25 =
150 m²
#### 5) Side = 12 cm
SA = 6 × (12)² = 6 × 144 =
864 cm²
#### 6) Side = 3 in
SA = 6 × (3)² = 6 × 9 =
54 in²
#### 7) Side = 7 cm
SA = 6 × (7)² = 6 × 49 =
294 cm²
#### 8) Side = 15 m
SA = 6 × (15)² = 6 × 225 =
1,350 m²
#### 9) Side = 10 m
SA = 6 × (10)² = 6 × 100 =
600 m²
#### 10) Side = 8 in
SA = 6 × (8)² = 6 × 64 =
384 in²
