Question

The volume of cuboid is 180cm its height is 5cm if the base is a sq find the side of the square box

Answer 1

Answer:

volume of cuboid =l×b×h=448cm

3

                             =l×b×7=448cm

3

 

                             =l×b=64cm

2

 

but base is square  

∴l=b

∴l

2

=64cm

2

⇒l=b=8cm

surface area =2(lb+lh+bh)

=2(8×8+8×7+8×7)

=2(64+56+56)

=352cm

Step-by-step explanation:

Answer 2

Answer: side's length is 6 cm

Step-by-step explanation:

Let, Side's length of square base = a cm

Cuboid's height = h = 5 cm

Then, we know that Volume of cuboid = a²h cubic cm

Now, a²× 5 =180

=> a² = 36

=> =cm

a=√36

, a = 6 ccm
