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:
84,030.00 (Move the decimal point 4 to the right)
Step-by-step explanation:
When multiplying, move the decimal to the right! When dividing, move the decimal to the right!
Since, 10,000 has 4 zeros, we will want to move the decimal point four places to the right!
Hope this helps! :)
Based on the calculations, the volume of this pyramid is equal to: C. 324 cubic centimeters.
<h3>How to calculate the volume of a pyramid?</h3>
Mathematically, the volume of a pyramid is calculated by using this formula:
Volume = 1/3 × base area × height
Next, we would determine the height of triangle ABC by using this formula:
Height = a × √3
Height = 6√3
Substituting the parameters into the formula for volume, we have;
Volume = 1/3 × 54√3 × 6√3
Volume = 1/3 × 972
Volume = 324 cm³.
