To find out how much water is left in the tank, we need to subtract the amount of water used from the total amount of water the tank can hold.
First, let's find the total capacity of the tank in cubic meters. The tank's dimensions are given as 2.5m by 4m by 5m, so the volume of the tank can be calculated by multiplying these dimensions together:
Volume = Length x Width x Height
Volume = 2.5m x 4m x 5m
Volume = 50m³
Therefore, the tank can hold a total of 50 cubic meters of water.
Next, we need to subtract the amount of water used (35m³) from the total capacity of the tank (50m³) to find the amount of water left:
Amount of water left = Total capacity - Amount used
Amount of water left = 50m³ - 35m³
Amount of water left = 15m³
Therefore, there is 15 cubic meters of water left in the tank.
