Question

A pile of 15 boxes is 3 metres high. What is the depth of each box?

Answer 1

Answer:

20

3 metres =300cm

therefore and since pile of 15 boxes is 300cm,

for one box , 300÷15

=20

please mark me brainliest

Answer 2

Answer: 200 millimetre

Step-by-step explanation:

Answer:  D) 200 mm

====================================================

Work Shown:

1 meter = 100 cm

3 meters = 300 cm (multiply both sides by 3)

15 boxes are 300 cm tall combined, so 300/15 = 20 cm is the height of each box.

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

Unfortunately 20 cm isn't listed as an answer choice, but we can convert to km and see what happens

20 cm * (1 m/100 cm)*(1 km/1000 m) = 20/(100*1000) = 0.0002 km

It's close, but off by a digit. Choice B has two zeros while 0.0002 has three zeros between the decimal point and the '2'.

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

Let's convert to mm and see what happens

20 cm * (10 mm/1 cm) = 200 mm

Through trial and error, we arrived at the final answe
