Question

Anand has a cubic box of volume 8,000 cm with open top. What is the surface area of this box?​

Answer 1

Volume = side^3

8000= side ^3

20^3 = side ^3

Side = 20 cm

Surface Area = 6a^2

= 6*20*20

=2400 cm ^2

Answer 2

Answer:

The surface area of the box will be 2000 cm²

Step-by-step explanation:

Here the volume of the cubic box is given to be 8000 cm³

We will first find the side of the cube

volume of cube = a³

                8000 = a³

                       a = ∛8000

                       a = 20 cm

Now, we have to find the surface area of the box, given that the top is open

So, the surface area will be the area of 5 surfaces

surface area = 5a²

                     = 5 × 20 × 20

                    = 2000 cm²
