Question

The volume of cuboid is 400 m3
. Find its length if its breadth and height are 5 m and 10
m.
a. 4m
b. 6m
c. 8m
d. 10m

Answer 1

Answer:    C

Explanation:

Vol. of cuboid = l*b*h

or, 400 = l* 5 * 10

or. l =400 /50

Hence, l= 8m

Answer 2

Answer:

Let length=l

breadth,b=5 m

height,h= 10 m

Volume of cuboid=400 m³

so, Volume of cuboid= length*breadth*height

=> 400= l* 5* 10

=> 400=50*l

=> l = 400/50

=8 m

so lenth of the cuboid is 8 m.(ans)
