Answer 3

Calculating the Mass of 8 Bricks

To calculate the mass of 8 bricks, each with a mass of 4 kg, we can use the following formula:

Total mass = Number of bricks × Mass of each brick

Substituting the given values: Total mass = 8 × 4 kg

Using the formula, we can calculate the total mass: Total mass = 8 × 4 kg = 32 kg

So, the mass of 8 bricks, each weighing 4 kg, is 32 kg.
