Calculating the Amount of Sand

To calculate the amount of sand in the soil, we can use the information provided. We know that the total amount of soil is 58 kg, and it consists of 20 kg of manure, 9 kg of ash, 2 kg of peat, and the rest is sand.

Given: - Total soil weight: 58 kg - Manure: 20 kg - Ash: 9 kg - Peat: 2 kg

We can calculate the amount of sand by subtracting the sum of manure, ash, and peat from the total soil weight.

Calculation: Total soil weight - (Manure + Ash + Peat) = Sand 58 kg - (20 kg + 9 kg + 2 kg) = Sand 58 kg - 31 kg = Sand Sand = 27 kg

So, there were 27 kilograms of sand in the soil.
