Answer:
2028 square inches
Explanation:
The side length of the styrofoam cube measures 6 1/2 inches.
Step 1
We find the surface area of a cube
The formula is given as
Surface Area = 6a²
Where a = Side length of the cube = 6 1/2 inches
Hence,
Surface area of a cube = 6 × (6 1/2inches)²
= 253.5 square inches
Step 2
Huy is painting eight styrofoam cubes for a science project.
The total surface area that Huy will paint is calculated as:
1 styrofoam cube = 253.5 square inches
8 styrofoam cubes = x
Cross Mulitiply
x = 8 × 253.5 square inches
x = 2028 square inches
Therefore, the total surface area that Huy will paint is 2028 square inches.
