Question

Two cube each side 4 cm are joined to form a cuboid the surface area of the resulting cuboid is

Answer 1

Answer:

Step-by-step explanation:

Here a cuboid of length 8cm breadth of 4 cm and height 4 cm will be formed.

now

TSA= 2(lb+bh+lh)

=2(4x8+4x4+4x8)

=2(80)

=160cm^2

Answer 2

side = 4 for cube

so length of cuboid = 8

breadth = 4

height =4

2lb+2bh+2lh = surface area of a cuboid

64 + 32 + 64 = 160 sq.cm
