Question

4. Two cubes each of edge 6m are joined face to face. The surface area of the cuboid thus formed is (a)200 cm
cm (c) 360 cm (d) 280 ​

Answer 1

Answer:

when cube are joined face to face

Step-by-step explanation:

length=6+6=12cm

b=6

h=6

now surface area of cuboid =2(lb+bh+hl)

2(12×6+6×6+6×12)=360cm

Answer 2

Answer:

answer is c 360 cm^2

Step-by-step explanation:

since one side of each cube will merge

surface area of each cube thereafter will be 5*6^2 & total surface area will be

2*5*6^2 = 360 cm^2
