building is 50cm long 38cm wide and 225cm tall on the model 1 centimeter represents 2.5 meters how tall is the actual building in meters?

The building model is :

50 cm long.

38 cm wide.

225 cm tall.

1 cm represent 2.5 meters

OR:

1 cm represent 250 cm.   (1 meter = 100 cm.)

Then the actual building is 250 times the model building:

Then the actual building is:

50*250 = 12500 cm= 125 m long

38*250=  9500 cm= 95 m wide

225*250 = 56250 cm = 562.5 m tall
