Question

a matchbox measures 4cm by 2.5 by 1.5 cm . what will be the volume of a packet containing 12 such matchbox

Answer 1

Answer:

Dimension of matchbox =4cm×2.5cm×1.5cm

l=4cm,b=2.5cm & h=1.5cm

Volume of cuboid =(l×b×h)

Volume of one matchbox =  Volume of cuboid

Volume of one matchbox =4×2.5×1.5=15cm3

Volume of a packet containing 12 such boxes = 12× volume of one match box

(12×15)cm3=180cm3

Hence, the volume of a packet containing 12

such boxes=180cm3
