Question

Three cubes each of volume 64cm cude are joined end to end find the surface area of resulting cuboid​

Answer 1

Answer:224 sq.m

Step-by-step explanation:

Answer 2

Answer:

Volume of 1 cube = 64cm cube = side cube

Each side=$\sqrt[3]{64}$ = 4cm

Now, by placing the three cubes [each with side 4cm] joined end to end

we get, length = 4*3 = 12cm

            breadth = 4cm

            height = 4cm

Now, SA of cuboid = 2[lb+bh+lh]

=2[12*4 + 4*4 + 4*12]

=2[ 48+16+48 ]

=2[ 112]

=160 cm sq.
