Calculate 6275

A block with edges of lengths of 10 cm and 8 cm has the same volume as a cube with an edge of the length of 1 dm. Calculate the third dimension of the block. Compare the ratio of the surfaces of both bodies.

Correct answer:

c =  12.5 cm

Step-by-step explanation:

a=10 cm b=8 cm  x=1 dm cm=1 10  cm=10 cm V=x3=103=1000 cm3 c=V/(a b)=1000/(10 8)=12.5 cm
