Question

Two cubes of size 4cm and 6cm are melted to form a cuboid of length 10 CM and breath 8cm .what is the height of the cuboid so found?

Answer 1

Area of small cubes is equal to biggest cubiod

so

(4×4×4)+(6×6×6)=10×8×h

64+216=80h

h=(280/8)

Answer 2

Step-by-step explanation:

a³+à³=4³+6³=64+216=280

area of cuboid= l.b.h=10*8*h=280

80*h=280

h=280/80=3.5
