Question

two cubes of side 4cm are joined to form a cuboid find its total surface ​

Answer 1

Step-by-step explanation:

earlier the length of cube = 4 cm

breadth = 4 cm

also height = 4cm

Now , when it is joined ,

new length = 8 cm

but breadth and height remain same

= 4cm each.

so it's total surface area = 2(l*b + b*h + h*l )

= 2( 8*4 + 4*4 + 4*8) cm²

= 2 (32+ 16+ 32)cm²

= 2 * 80 cm²

= 160 cm²

hope it helps
