Question

A cuboid has volume of 120cm³
The area of the base of the cuboid is 30cm²
Find out the surface area of the cuboid ​

Am I correct that this is unsolvable?

Answer 1

$\huge\bold\purple{Answer}$

volume of cuboid = lx b x h = 448cm3

=l x b x 7== 448cm3

=lxb= 64cm2

but base is square

l= b

.:.l2 = 64cm

l=b= 8cm

surface area = 2(lb+ bh+ b)

= 2(8 x 8+ 8 x 7+8 x 7)

= 2(64+ 56+ 56)

= 352cm
