Question

A Cubical box having dimensions 1.5m each is open from the top. Calculate the total Surface Area .??
plz find this ....​

Answer 1

Step-by-step explanation:

1.5m = 150cm

first we find total surface area:-

surface area of cube = 6 × side^2

= 6 × 150^2

= 135000cm

the cube is open to the top

so, area of square = side × side = (side)^2

= 150^2

= 22500cm

therefore,

total surface area of open cube = area of cube - area of square

= 135000 - 22500

= 112500cm

= 1125m^2
