Two similar solids a and b are shown solid a has a volume of 60cm3

A) 480cm^3

B) 35 cm^2

Step-by-step explanation:

Given two similar solids

Volume of A = 60cm^3

Surface area of B = 140cm^2

Side A = 3

Side B = 6

NB: if two solids are similar, the ratio of their volume equals the cube of the corresponding proportion of their linear measure.

That is :

Volume A / volume B = (side A / side B)^3

(60 / volume B) = (3 / 6)^3

(60 / volume B) = (1/2)^3

(60 / volume B) = (1/8)

Volume B = 480cm^3

B) the surface area:

NB: if two solids are similar, the ratio of their surface areas equals the square of the corresponding proportion of their linear measure.

Surface area A / surface area B = (side A / side B)^3

(surface area A / 140) = (3 / 6)^2

(surface area A / 140) = (1/2)^2

(surface area A / 140) = 1/4

4 × surface area A = 140

Surface area A = 140/4

Surface area of A = 35cm^2
