Question

A cavity of 5m*3m*2m is filled with sand. The cost of one cubic meter of sand is Rs. 500. Total cost to fill the cavity is? A) 15,000 B) 30,000 C) 50,000 D) 53,000

Answer 1

Answer:

15000/-

Step-by-step explanation:

the volume of cavity is 5m*3m*2m=30m^3

to fill 1m^3 of cavity is 500/- then

to fill 30m^3 if cavity is=(30*500)/1

                                    = 15000/- rupees

Answer 2

Given :-

• Length = 5m

• Breadth = 3m

• Height = 2m

• Cost per cubic metre = Rs. 500

Answer :-

• Rs. 15,000

Solution :-

$\small\sf{\boxed{Total\:Cost\:=\:(Volume \:of\: cavity)\times500}}$

$\small\sf{\boxed{Volume\:=\:Length\times Breadth\times Height}}$

${}$

$\implies\sf{Total\:Cost\:=\:(5\times3\times2)\times500}$

${}$

$\implies\sf{30\times500}$

${}$

$\implies\sf{Rs.15000}$

${}$

$\sf{\underline{So\:total\:cost\:to\:fill\:the\: cavity\:is\:Rs.15000}}$
