Question

three cubes each having an edge 4 cm are joined together find the surface area of cuboid thus formed

Answer 1

hiii!!!

here's ur answer...

if the three cubes of edge 4cm are joined then it will form a cuboid whose length will be

=4+4+4+4

=16cm

TSA of the cuboid formed=2(lb+bh+lh)

=2[(16×4)+(4×4)+(16×4)]

=2(64+16+64)

=2×144

=288cm²

hope this helps..!

Answer 2

Answer:

Step-by-step explanation:

If we combine three cubes of edge 4cm

Then length of formed cuboid(L) = 4+4+4= 12cm

B=H=4cm

T.S.A= 2(LB+BH+HL)

=2(12*4+4*4+12*4)

Ans....=224cm^2
