Question

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

Answer 1

Answer:

Step-by-step explanation:

gn,

volume of cuboid= 105$cm^3$

area of its square face = 45$cm^{2}$

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$\sqrt{5$cm

base = height = 3$\sqrt{5$cm

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 !!!!!!
