A) 31 :46
B) 43 :56
C) 31:56
D) none of these
Correct Answer: C
Solution :
[c] Surface area \[=2\text{ }\left[ 16\times 14+14\times 7+16\times 7 \right]\text{ }c{{m}^{2}}=868\text{ }c{{m}^{2}}\] Volume \[=\left( 16\times 14\times 7 \right)\text{ }c{{m}^{3}}=1568\text{ }c{{m}^{3}}\] \[\therefore \] Numerical ratio of surface area and volume is 868 : 1568 or 31 : 56You need to login to perform this action.
