Step-by-step explanation:

----------------------------------------------------------------------

Yes, it is a resonable estimate,

Dimensions of the garage= 6m,4m,2.5m,

Dimensions of brick=22 cm,10 cm,7 cm,

So,first convert m to cm : 1m=100 cm,

600 cm,400 cm,250 cm,

= 600×400×250,

60000000 cm².

22 cm,10 cm,7 cm,

22×10×7,

1540 cm².

So, number of bricks= 60000000/1540,

38961 bricks are required which are less than 40000 bricks.

Answer 2

Answer:

No as,

Step-by-step explanation:

Volume of each wall= 6*4*2.5=60

Total volume of each wall= 60*6=360m^3

360m^3=360000000cm^3

Volume of each brick= 22*10*7=1540

Number of bricks required= 360000000/1540=233766.2338

Therefore, 233766.2338 is more than 40000 thus, the estimation is wrong.

She must have skipped the part of x6 at the total volume.
