Question

Given that 1 cubic cm of marble weighs 0.25kg,the weight of marble block 28cm in width and 5cm thick is 112kg.Find length of the block

Answer 1

Answer:

Volume of marble =28 ✖ 5✖h then weight of 1marble =0.25kg so weight of marble =28✖5✖h✖0.25=112 so h=3.2

Answer 2

Length of the marble block = 3.2 cm

Step-by-step explanation:

We are given the following information in the question:

Weight of marble block =  112 kg

Width of marble block = 28 cm

Height of marble block = 5 cm

Density of marble block:

1 cubic cm = 0.25 kg

We have to find the length of the marble block.

Volume of marble block =

$\text{Volume of cuboid} = \text{Length}\times \text{Width}\times \text{Height}\\= \text{Length}\times 28\times 5\text{ cubic cm}$

Weight of marble block =

$=\text{Volume of marble block}\times \text{Density}\\\Rightarrow \text{Length}\times 28\times 5\times 0.25 = 112\\\Rightarrow \text{Length} = \displaystyle\frac{112}{28\times 5\times 0.25} = 3.2\text{ cm}$

Thus, the length of the marble block is 3.2 cm
