Question

the volume of a wooden block is 4,500cm3 .if it is 30cm long and 15 cm wide,then find its height

Answer 1

given v=4500
volume = length × breadth × height
v = 30 × 15 × h
h = 4500/30×15
h = 150/15
h = 10cm

Answer 2

Given: Volume of wooden block = 4,500 $cm^{3}$

           Length of block = 30cm

           Breadth of block = 15cm

To find: Height of the wooden block

Solution: Given that,

Volume of wooden block which is cuboid in shape = 4,500 $cm^{3}$

Length = 13cm and Breadth = 15cm

Height = ?

∵ $Volume \ of \ cuboid = Length \ * \ Breadth \ * \ Height$

⇒ 4,500 = 30 × 15 × Height

⇒ Height = $\frac{4500}{30 \ * \ 15} = \frac{4500}{450} = 10$

Hence, height of the wooden block is 10cm.
