Step-by-step explanation:
Where are the options
Well... - 9x+4y
Less than 2 = z < 2
Less than or equal to 8 = z ≤ 8
z ≤ 8
z < 2
Surface area of a cube = 486 square inches
Solution:
Given each side of a cube = 9 inches
Net of a cube has 6 squares.
Area of square = side × side
Area of 1 square = 9 × 9 = 81 square inches
Surface area of a cube = Area of 6 squares
= 6 × (side × side)
= 6 × 81
= 486 square inches
Hence, surface area of a cube is 486 square inches.
Answer:
<em>The answer is B.</em>
