5 bags of plaster cover 35m2 what will 7 bags cover
First you divide 35 by 5 to get 7 so each bag covers 7m2 then multiply 7 by 7 to get 49.
So 7 bags would cover 7m2
First we need to divide 35 m² by the total 5 bags;
35m² ÷ 5 = 7m²
So now lets multiply 7m² by 7 total bags;
7m² × 7 = 49m²
So your final answer is... 49m²
