Volume of cuboid is 105cm cube and area of square face is 45cm square.find length of cuboid​

Answer»

Answer:

Step-by-step explanation:

gn,

volume of CUBOID= 105cm^3

area of its SQUARE face = 45cm^{2}

sol,

area of its square face =base of cuboid * HEIGHT of cuboid

hence , height = base and let the side of the square face be "s".

area of square =s^{2}\\

s^{2}=45

s=\sqrt{45

s=3\sqrt{5cm

base = height = 3\sqrt{5cm

volume of cuboid= LENGTH * base * height

                       105 =length * 3\sqrt{ 5*3\sqrt{5

                       105= l* 45

                       105/45 = l

                  length = 2.34cm  (approx)

i hope my answer helps u !!!!!!
