Answer:
10cm × 6cm=60cm²
60÷(10×2)=3cm
Step-by-step explanation:
We take the area of the block, that is, 10cm × 6cm =60cm²
This area is also the volume of the block unless any other height is mentioned. When it is melted and reshaped, the volume remains the same same, that is 60cm³.
Volume = length×breadth×height
=>60 = length×10×2
=>length = 60÷(10×2)
=>length = 60÷20 = 3 cm
