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.

Oh, honey, it looks like you've got yourself a rectangular prism there. To find the surface area, you calculate 2lw + 2lh + 2wh. So, for your dimensions of 7cm, 5cm, and 8cm, the surface area would be 2(75) + 2(78) + 2(5*8) = 10 + 112 + 80 = 202 square centimeters.

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

Well, darling, to find the volume of a cuboid, you simply multiply its length, width, and height. So, for this sassy little cuboid measuring 5cm by 6cm by 7cm, the volume would be 5 x 6 x 7 = 210 cubic centimeters. Voilà!
Oh, what a happy little question! Imagine a beautiful cuboid with sides 5cm by 3cm by 6cm. Now, gently sketch a net of this cuboid by drawing a rectangle for the top and bottom, and rectangles for the sides. Label each side with its corresponding dimension, and remember to add tabs for gluing it all together. Just let your imagination flow and create a lovely net that showcases the dimensions of this cuboid.
SA = 150 cm2
It is 6/5 or 1.2/1
The surface area is 150 cm2
