Question

.6. If two cubes each of edge 3 units are joined end to end, then what are the dimensions of
the resulting cuboid? Make an isometric sketch of this cuboid.

Answer 1

Step-by-step explanation:

Given if two cubes each of edge 3 units are joined end to end, then what are the dimensions of the resulting cuboid?  

• So 2 cubes each of edge 3 units are joined end to end, so its height will be 3 units, length will be 3 units and breadth will be 3 units.
• So curved surface area of cuboid = 2h(l + b)
•                                                     = 2 x 3 (3 + 6)
•                                                      = 6 x 9
•                                                      = 54 sq cm
• So total surface area of cuboid = 2 (lb + bh + lh)
•                                                  = 2(3 x 6 + 6 x 3 + 3 x 3)
•                                                   = 2(18 + 18 + 9)
•                                            = 2 x 45
•                                           = 90 sq cm

Answer 2

Answer:

So, let

Length =3 as in question

if we want to make cuboid so

Length =3+3 =6units

breadth=3

Height =3

Isometric sketch will be in the shape
