VikaD [51]

Answer:

Option D

Step-by-step explanation:

$F=\frac{9}{5}C+32\\\\F-32=\frac{9}{5}C \\\\5(F-32)=9C\\\\\frac{5(F-32)}{9}=C \\\\C=\frac{5}{9}( {F-32})$

For F=77°F

$C=\frac{5}{9}(F-32) \\\\C=\frac{5}{9}(77-32)\\\\C=\frac{5}{9}(45)\\\\C=\frac{225}{9} \\\\C=25$

SA (I assume total surface area) = $66.59 m^{2}$

V (volume) = $32 m^{3}$
