A farmer is painting a new barn. He will need to calculate the surface area of the barn to purchase the correct amount of paint. In which of the following units can the farmer expect to calculate the surface area?

Question

yd2
yd
m3
m

Answer 1

The farmer will calculate the surface area of the barn in square units. The appropriate unit for surface area is square yards (yd²) or square meters (m²).

Among the options you provided:

• yd² (square yards) is the correct unit for surface area.
• yd (yards) measures length, not area.
• m³ (cubic meters) measures volume, not area.
• m (meters) measures length, not area.

Therefore, the farmer can expect to calculate the surface area in yd².
