See the solution process below:

Explanation:

The formula for the volume of this cube is:

#V = L xx W xx H#

Substituting for #L#, #W# and #H# gives:

#V = 9.25 xx 4.75 xx 3#

#V = 43.9375 xx 3#

#V = 131.8125#

The formula for the surface area is:

#S = 2(L xx W) + 2(L xx H) + 2(W xx H)#

Substituting for #L#, #W# and #H# gives:

#S = 2(9.25 xx 4.75) + 2(9.25 xx 3) + 2(4.75 xx 3)#

#S = (2 xx 43.9375) + (2 xx 27.75) + (2 xx 14.25)#

#S = 87.875 + 55.5 + 28.5#

#S = 143.375 + 28.5#

#S = 171.875#
