40 cans

Answer 1

4

Explanation:

10 walls that are each 100sqfeet totals to 1000sqfeet. 1000/250 is equal to 4 cans.

Answer 2

• 4 cans

Solution:

We know that:

• Apartment = 10 walls
• 1 wall = 100 sq. feet
• 1 can = 250 sq feet

Solution:

• 1 wall = 100 sq. feet
• => Apartment = 10 walls = 100 x 10
• => Apartment = 10 walls = 1000 sq. feet
• => 1 can = 250 sq feet
• => x cans = 250x = 1000
• => 250x = 1000
• => x = 4

Hence, 4 cans are required to paint the apartment.
