Answer: 54 bricks

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a rectangular prism (V) : length x width x height

Replacing with the values given and solving for v (Volume)

V = 10 x 6 x 4

V = 240 cm3 (volume of one brick)

Finally, we have to divide the amount of concrete used by the volume of each brick:

13,000cm³ / 240 cm3 = 54.16 = 54 bricks
