Match the following figures:
Answer
$\therefore$ Area of the rectangular face sith sides 4.
Thus, the net for given figure will have four faces with area 24 and two faces with area 9.
Observe that net (i) satisfies this.
Thus, the net of figure (b) is net (i).
$\therefore$ Area of the rectangular face sith sides 3 and 4 = 3 × 4 = 12,
Area of the rectangular face with sides 4 and 6 = 4 × 6 = 24
And, area of the other face with sides 3 and 6 = 3 × 6 = 18
Thus, the net for given figure will have two faces with area 24, two faces wit area 18 and two faces with area 12.
Observe that net (ii) satisfies this.
Thus, the net of figure (c) is net (ii).
$\therefore$ Area of the rectangular face with sides 3 and 3 = 3 × 3 = 9, And
area of the other face with sides 3 and 9 = 3 × 9 = 27
Thus, the net for given figure will have four faces with area 27 and two faces with area 9.
Observe that net (iii) satisfies this.
Thus, the net of figure (d) is net (iii).
View full question & answer→- The given figure is a cuboid with sides 4, 4 and 6 units.
$\therefore$ Area of the rectangular face sith sides 4.
- The given figure is a cuboid with sides 3, 3 and 8.Area of a rectangle = length × width
Thus, the net for given figure will have four faces with area 24 and two faces with area 9.
Observe that net (i) satisfies this.
Thus, the net of figure (b) is net (i).
- The given figure is a cuboid with sides 3, 4 and 6.
$\therefore$ Area of the rectangular face sith sides 3 and 4 = 3 × 4 = 12,
Area of the rectangular face with sides 4 and 6 = 4 × 6 = 24
And, area of the other face with sides 3 and 6 = 3 × 6 = 18
Thus, the net for given figure will have two faces with area 24, two faces wit area 18 and two faces with area 12.
Observe that net (ii) satisfies this.
Thus, the net of figure (c) is net (ii).
- The given figure is a cuboid with sides 3, 3 and 9.
$\therefore$ Area of the rectangular face with sides 3 and 3 = 3 × 3 = 9, And
area of the other face with sides 3 and 9 = 3 × 9 = 27
Thus, the net for given figure will have four faces with area 27 and two faces with area 9.
Observe that net (iii) satisfies this.
Thus, the net of figure (d) is net (iii).
