Question

THE AREA OF THE BASE OF A CUBOID IS 44CM SQ.FIND THE HEIGHT,IF THE VOLUME IS 378.4 CM CUBE

Answer 1

 Area of base of cuboid  = Area of rectangle
 
Therefore l * b = 44 cm ²  --------(1)

Volume of cuboid = l * b * h
 substitute l*b as 44    [ from (1) ] 

378.4 cm³ = 44 cm² * h
=> h = 378.4 cm³ / 44 cm²
= h = 8.6 cm

Therefore height of the cuboid = 8.6 cm

Hope it helps!!
Cheers!!

Answer 2

It will be the length =8.6cm
