Want this question answered?
There seems to be some confusion about dimensions in this question. Area is a two dimensional concept, there are three dimensions given for the shape in question. It is possible that the object is a cuboid and the question concerns the surface area of the cuboid. Or the shape could be a triangle whose area is required. Unfortunately, there are too many different alternatives to try second guessing the question's intent.

The surface area is 750 cm^3
coz
The total surface area is 2*(5*5 + 5*15 + 15*5) = 2*175 = 350 cm2

SA = 150 cm2
The surface area is 150 cm2
It is 6/5 or 1.2/1

Find the volume of a cuboid of length 7cm breath 5cm and height 6cm
2cm*5cm*3cm=30cm3The volume of the cuboid: 2*5*3 = 30 cubic cm
