Question

\(2\) cubes each of volume \(64cm^3\) are joined end to end. Find the surface area of the resulting shape.

Answer 1

i think this shape must be cuboid :/

Answer 2

yeah .. it's a cuboid. first find the length of side of it.

Answer 3

Volume = \(a^3\) = \(64cm^3\)
\(a\) = \(\sqrt{64cm}\) = \(4cm\)

Answer 4

yep .. now let's visualize the picture of two cuboid joined together.

Answer 5

so h=4cm, b=4cm but l=4+4=8cm ?

Answer 6

Area = 4(s*2s)+2*s^2 where\[s=\sqrt[3]{64}=4 \]

Answer 7

you know how to find surface area of one cuboid right??

Answer 8

yes :) Thanx everyone :)

Answer 9

You guys are so amazing ;)
