Answer 1

Question :

A watering can holding 7kg of water can water 4000 potted plants. How much water is needed for a single plant in a pot

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Answer :

Formula used :

★ Mass of one plant = Water can hold ÷ Water can potted plants

★ volume of water needed = mass of plant × 1000 ÷ 1g/ml

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Given :

❖ Water can hold = 7kg

❖ Water can potted plants = 4000

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Solution :

We have ,

7kg water for 4000 plants

Mass of one plant = water can hold ÷ water can potted plants

$\blue{: \leadsto} \: \: \orange{\dfrac{7}{4000}}$

$\large{\blue{:\leadsto} \: \red{\boxed{\orange{0.00175}}}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Density of water = 1g/ml

Volume of water needed = mass of plant × 1000 ÷ 1g /ml

$\blue{:\leadsto} \: \orange{\dfrac{0.00175 × 1000} {\dfrac{1g}{ml}}}$

$\blue{:\leadsto} \: \orange{1.75 \times \dfrac{ml}{1g}}$

$\large\blue{:\leadsto} \: \red{\boxed{\orange{1.75ml}}}$

Therefore, Volume of water needed = 1.75ml
