e) Find the coordinates of the midpoint of AC
i) (3,0) ii) (6,4) iii) (0,3) iv ) (4,6)

Answer 1

Answer:

The dimensions of match box are 4 cm×2.5 cm×1.5 cm

∴ length =4 cm

breadth =2.5 cm

height =1.5 cm

Now,

Volume of = length × breadth × height

One match box =4 cm×2.5 cm×1.5 cm

=15 cm

3

∴ Volume of one match box =15 cm

3

⇒ Volume of 12 match boxes +12× Volume of one match box

=12×15 cm

3

=180 cm

3

∴ Volume of packet containing 12 match boxes =180 cm
