Question

a rectangular block of metal measuring 4cm by 5cm by 6cm was melted down to make a block 8cm by long by 3cm wide. how high was the block.

Answer 1

Both are cuboid let l1=4,b1=5,h1=6

l2=8,b2=3,h=?

volume of first block = volume of second block
l1 * b1 * h1=l2*b2*h2

4 * 5 * 6 = 8 * 3 * h2
120 = 24 * h2
h2= 120/24
h2 =5cm
