Question

Two cubes, each of volume 343 cm are joined end to end. Find the surface area of
the resulting cuboid,​

Answer 1

Step-by-step explanation:

volume of each cube =343cm

side =

$\sqrt[3]{343} = 7$

side of resulting cube =7+7=14cm

surface area of resulting cube =2(lb+bh+lh)=2(14×7+7×7+14×7)=2(98+49+98)=2×245=490cm
