Question

• A matchbox measures 4 cm x 2.5 cm x 1.5 cm. What will be the volume of a packet containing 12 such boxes? A cuboidal water tankis 6 m long 5 m wide and 45 m deep. How many litres of water​

Answer 1

Step-by-step explanation:

1)volume of packet containing 12 boxes = [12×(4×2.5×1.5) ] cm³

= 180 cm³

2) litres of water= (6×5×45)m³

= 1350 m³

Answer 2

Answer:

Volume of 1 matchbox = l×b×h

l = 4cm

b = 2.5cm

h = 1.5cm

Volume of matchbox = 4×2.5×1.5 cm³

                                   = 15 cm³

Volume of 12 matchbox = Volume of one matchbox × 12

                                        = 15×12 cm³

                                        = 180 cm³
