The width of solid is b = 3 cm

Step-by-step explanation:

Given that

length = 2 × width

length = 2 × height

⇒ L = 2 b ------- (1)

⇒ L = 3 h ------- (2)

⇒ 2 b = 3 h

h = \frac{2 b}{3} ------- (3)

Volume = 36 cm^{3}

The volume of solid is given by the formula,

⇒ L× b × h = 36

Put the value of L and h from equation (1) & (3), we get

⇒ 2 b × b × \frac{2 b}{3} = 36

⇒ 4 b^{3} = 108  

b^{3} == 27

⇒ b = 3 cm

Thus the width of solid is b = 3 cm
