Question

a metalic rectangular block is 5m long 3m wide and 2m thick. if a cubic metre of metal weighs 10g what is the weight of the block

Answer 1

Answer:

length = l = 3m = 300 cm

breadth = b = 1.5 m = 150 cm

height = h = 3 m = 300 cm

Volume of the solid piece = l × b × h = 300 × 150 × 300 = 13500000 cm3

weight of 1 cm3 solid = 7 g

weight of 13500000 cm3 solid = 94500000 g = 94500 kg  

I Hope it will help!

Answer 2

$<b> Hello</b>$
Given:
======
length=5m

Breath/width=3m

height/thick=2m


Weight of cubic meter =10g


Step 1:Find the volume
===================°==°°°°

The Given figure is Cuboid.

So, volume of Cuboid=L×B×H

=5×3×2

=30cubic meter

step 2
====================
Now to find total weight

Multiply 30 and 10

=30×10

=300g


So, total weight of BLOCK is 300gram
