Question. 29 A cube of side 4 cm is painted on all its sides. If it is sliced in 1 cu cm cubes, then number of such cubes that will have exactly two of their faces painted, is_______.
Solution. 24
The volume of a cube of side 4 cm = 4 x 4 x 4 = 64cm3 When it is sliced into 1 cm3 cubes, we will get 64 small cubes.
In each side of the larger cube, the smaller cubes in the edges will have more than one face painted.
The cubes which are situated at the corners of the big cube, have three faces painted.
So, to each edge two small cubes are left which have two faces painted. As, the total number of edges in a cube are 12.
Hence, the number of small cubes with two faces painted = 12 x 2 = 24

These two cubes are joined face-to-face, then the resultant solid figure is a cuboid which has same breadth and height as the joined cubes has length twice of the length of a cube, i.e. l = 2a,b= aandh = a
Thus, the total surface area of the cuboid = 2 (lb + bh + hi)
= 2 (2a x a + a x a + a x 2a)
= 2 (2 a2 + a2 + 2 a2)=2 x 5 a2 = 10a2

...Total surface area of a cylinder = Curved surface area + Area of top surface + Area of base
= 2 x π x Radius x Height + π (Radius)2+ π (Radius)2
= 2πhr+ πh2 + πh2
= 2πrh + 2πh2
= 2πh(r + h)

Since, all the faces of a cube are squares of same side length, therefore the areas of any two faces of a cube are equal.

Question. 54 The areas of any two faces of a cuboid are equefl.
Solution. False
A cuboid has rectangular faces with different lengths and breadths. Only opposite faces of cuboid have the same length and breadth.
Therefore, areas of only opposite faces of a cuboid are equal.

Question. 55 The surface area of a cuboid formed by joining face-to-face 3 cubes of side x is 3 times the surface area of a cube of side x.
Solution. False
Three cubes having side x are joined face-to-face, then the cuboid so formed has the same height and breadth as the cubes but its length will be thrice that of the cubes.
Hence, the length, breadth and height of the cuboid so formed are 3x, x and x, respectively. Then, its surface area = 2 (lb + bh + hl)
= 2(3x x x + x x x + x x 3 x )=2(3xx2 + 3x2)
= 2 x 7x2 = 14x2
Now, the surface area of the cube of side x = 6 (Side)2 = 6x2 Hence, the statement is false.

Question. 56 Two cuboids with equal volume will always have equal surface area.

Question. 57 The area of a trapezium becomes 4 times, if its height gets doubled.
Solution. False
We know that,
Area of a trapezium = 1/2 (a + b) x h
where, a and b are the lengths of parallel sides and h is the altitude (height).
Now, if the height gets doubled, then
Area of trapezium = 1/2(a + b) x 2h = 2(1/2(a + b) x h)
Hence, the area is doubled.
So, the statement is false.

Question. 58 A cube of side 3 cm painted on all its faces, when sliced into 1 cu cm cubes, will have exactly 1 cube with none of its faces painted.

Then, the dimensions of the cube, so formed are 1 x 1 x 1.
...The surface area of the cube so formed = 6 (Side)2 = 6 x (1)2 = 6sq units
Hence, the surface area of the sliced cube is 6 sq units.

Question.61 Ratio of area of a circle to the area of a square whose side equals radius of circle, is 1 : TC.
