Given,
A tea packet measures 10cm x6cm x4cm.
To Find,
How many such packets can be placed in a cardboard box of dimensions 12cm x10cm x12cm.
Solution,
Length of tea packet = 10 cm
Breadth of tea packet = 6 cm
Height of tea packet = 4 cm
Therefore volume of one tea packet = lbh
= 10 x 6 x 4
= 240cm³
Length of carboard box = 12 cm
Breadth of carboard box = 10 cm
Height of carboard box = 12 cm
Volume of the carboard box = lbh
= 12 x 10 x 12
= 1440cm³
No. of packets that can be stored =
=
= 6
Therefore 6 packets can be stored in the box.
Formulas used:
→ Volume of cuboid
Surface areas and volume of cuboid:
→ LSA = 2 (lh + bh)
→ TSA = 2 (lh + bh + lb)
→ Volume = lbh
