Answer:
The weight of this sand pit when it is full of sand is 41.16kg
Explanation:
For the first sand pit
It weighs 6kg and weight increases to 50kg when filled with sand.
Therefore, it can hold 50kg - 6kg = 44kg of sand
For the second sand pit
From the question, it is 14% heavier, that is, the weight will be
6kg + (14/100) × 6kg = 6kg + 0.84kg
= 6.84kg
∴ The weight of the different sand pit is 6.84kg
Also from the question, it holds 22% less sand, that is, the weight of the sand it holds will be
44kg - (22/100) × 44kg = 44kg - 9.68kg
= 34.32kg
∴The weight of sand it holds is 34.32kg
The weight of this sand pit when it is full of sand is the sum of the weight of the sand pit and the weight pf sand it holds, that is,
Weight of sand pit = 6.84kg + 34.32kg = 41.16kg
Hence, the weight of this sand pit when it is full of sand is 41.16kg
