The surface of a cube with an edge of 9 cm was painted with paint weighing 117 g. How many grams of paint

The surface of a cube with an edge of 9 cm was painted with paint weighing 117 g. How many grams of paint would be required to paint the surface of a cube with an edge of 3 cm?

First, we find out how much paint is consumed per cm.

For this, we divide 117 g of paint by 9 cm.

117: 9 = 13.

So, we learned that 13 g of paint is consumed per 1 cm.

The next question is: How many grams of paint do you need per 3 cm?

So further, we take 3 cm and multiply by 13 g.

3 × 13 = 39.

Answer: 39 grams of paint.
