Answer:
A = 549.9 cm²
Step-by-step explanation:
Use the equation for surface area of a hexagonal prism
A = 6(5)(14) + 3√3 (5)² Multiply and simplify the exponent
A = 420 + 5.196(25) Multiply
A = 420 + 129.9 Add
A = 549.9 cm²
Answer:
C. 40 cm
Step-by-step explanation:
length of side of square = s
perimeter = s + s + s + s = 4s
We use the formula P = 4s
P = 4 * 10 cm
P = 40 cm
Answer: The perimeter is 40 cm.
Notice that the perimeter is a sum of lengths, so its units are linear units such as cm, inches, feet, a unit of length.
An area has square units such as cm^2, in.^2, ft^2, etc.
