Answer:
Therefore, the dimensions of the cardboard are 12cm, 6cm, and 2 cm
Step-by-step explanation:
Length of sheet = 16 cm
Breadth of sheet = 10 cm
Side of each square = 2 cm
∴ Inner length = 16−2×2=16−4=12cm
Inner length =10−2×2=10−4=6cm
By folding the sheet, the length of the container = 12 cm, breadth = 6 cm, height = 2 cm
∴ Volume of the container = (l×b×h)
=6x10x2
=60x2
=120 cm2
