Best to ask, "How do I solve this equation for n?"
1. Div. both sides by -4, along the way to isolating 8n-3 and then n:
8n-3 = -21
2. Add 3 to both sides: 8n = -18
3. Solve for n: n = -18/8 = -9/4 (answer)
Answer:
The formula of the surface area of a cube is 6 x s²
→ s = 9
→ s² = 9²
→ s² = 81
→ 6 x 81 = 486
So, the surface area of the cube is 486 units².
