A) 9
B) 13.5
C) 8
D) 9.5
Correct Answer: B
Solution :
Volume of rectangular block of ice \[=(40\times 25\times 15)c{{m}^{3}}=15000c{{m}^{3}}\] Now, weight of \[\text{1 c}{{\text{m}}^{\text{3}}}\]of water=1gm Weight of \[\text{1 c}{{\text{m}}^{\text{3}}}\] of ice \[\text{=}{{\left( \frac{9}{10} \right)}^{th}}\] of weight of \[\text{1 c}{{\text{m}}^{\text{3}}}\] of water \[\therefore \] Weight of \[\text{1 c}{{\text{m}}^{\text{3}}}\] of ice \[\text{=}\left( \frac{9}{10} \right)gm\] \[\therefore \] Weight of rectangular block of ice \[=\left( \frac{9}{10}\times 15000 \right)gm=13.5kg\]You need to login to perform this action.
