The volume of a cuboid is 1440 cm³. Its height is 10 cm long and the cross section is a square. Find the side of the square.

volume = base area x height
or, 1440 = A x 10
or, A = 144 cm2

let the side of the square be s
now, s2 = A = 144cm​2
or, s = 12 cm

Volume of a cuboid=(Area of its cross section)?height

1440=Area of cross section?10

144=Area of its cross section

A/Q-

Area of Cross Section is square
Let the side be x

Area=(Side)^2
144=x^2
12=x

Hence,Side=12

We know that,
Volume= base area*height
1440=a*10
1440/10=a
144cm2

Side of square be s
S2 =a
S2=144
S=?144
Side of square=12cm
