Test: Building With Bricks - 4 - Class 4 MCQ

Points G and E appear to lie on the same line that is similar to line m.

Among all the given options, option [C] cannot be the three pieces of the cube.

Perimeter of square P = 4 ×side = 4×6=24cm Perimeter of rectangle Q = 2 (Length + Breadth)
= 2 (8 + Breadth)

We are given Perimeter of P = Perimeter of Q ⇒24 = 2(8 + Breadth)

⇒24=16+2 ×Breadth

⇒2 × Breadth = 8

⇒Breadth = 4 cm

The three points will form a straight line.

      
Number of cubes in layer 1=8  Number of cubes in layer 2=8 Number of cubes in layer  3=8 Total number of cubes = 24

Counting the sides of the shaded squares while keeping in mind that common sides are not counted twice.

Figure in option [D] have a line symmetry.

A line of symmetry is a line that cuts a shape exactly in half.  

This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged. 

Two or more lines are said to be intersecting if they meet each other at a point. Here, Figure 2 and Figure 3 shows intersecting lines.

Perimeter of the given figure = 5 + 2 + 2 + 3 + 5 + 4 + 2 + 1 = 24cm

Figure in option [B] has exactly 6 faces.
