Q.8: A brick has volume of 180 cu cm. If the height of the brick is 6 cm, breadth is
3 cm. then its length is
a) 10 cm
b) 15 cm
c) 12 cm
d) 18 cm​

Answer 1

Answer:

l=10cm

Step-by-step explanation:

volume of cuboid =l*b*h

given volume =180cm3

b=3cm

h=6cm

so,

l*3*6 =180

l*18=180

l=180/18

=10cm

Answer 2

Answer:

volume of cuboid (brick) =L ×B×H

180cm^3= 6cm ×3cm ×L

180cm^3/18cm^2 = L

10 cm = L

therefore length of brick is 10 cm

Step-by-step explanation:

to check L=10 cm

B=3cm

H =6cm

volume of cuboid (brick) =L ×B×H

=10 cm × 3cm × 6cm

= 180cm^3
