Question

a volum of a block of gold is 0.5 m qubick. if it is hammered in to a sheet to cover an area of 2 hectars field​

Answer 1

Answer:

Let the length of sheet be l metres

Let the breadth of sheet be b metres

Let the thickness of sheet be h metres

Area of Sheet = 1 hectare

l x b = 1 x 10000 m. sq.

= 10000 m. sq.

if l x b = 10000 m.sq.

Then,

Volume of sheet = Vol. of Block

l x b x h= 0.5 m. cu.

(l x b) x h= 0.5 m.cu. (10000 m. sq.) x h=0.5 m. cu.

h=0.5/10000 m

h=0.000005 m

h=0.000005 x 100 x 10

h=0.05 mm

Thickness = Height

=0.05 mm

Step-by-step explanation:

First, Let the dimensions be l,b and h.

Second,Find the value of L x B by finding area of sheet.

Third,we know that vol. of sheet equals to vol.of block. Then,Put the value of l x b on vol.of sheet to find Height.

Fourth,Change the value of volume of sheet from m into mm by multiplying 100 x 10 with obtained answer.

Fifth, We know that height equals to thickness, so equal them and write the answer.
