Question 2 Mensuration Exercise 18.3

Fill in the following blanks:

Volume of cuboid Length Breadth Height
(i) 90 cm3 - 5 cm 3 cm
(ii) - 15 cm 8 cm 7 cm
(iii) 62.5 m3 10 cm 5 cm -

Answer:

Volume of cuboid = length x Breadth x Height

(i) 90 cm3 = length x 5 cm x 3 cm

Length = 90/(5 x 3) = 90/15 = 6 cm

(ii) Volume = 15 cm x 8 cm x 7 cm

= 840 cm3

(iii) 62.5 m3 = 10 m x 5 m x height

Height = 62.5/(10 x 5) = 1.25 m

Volume of cuboid Length Breadth Height
(i) 90 cm3 6 cm 5 cm 3 cm
(ii) 840 cm3 15 cm 8 cm 7 cm
(iii) 62.5 cm3 10 cm 5 cm 1.25 cm
