If the dimensions given are the length and the width, the area is determined by multiplying the length X width (5 X 3 = 15 sq cm).
For it to be a right angle triangle the 3rd side must be 5cm
Mean = sum(X)/n = 15cm/5 = 3cm
You cannot, because you have no information on the shape: is it a 2-d triangle or a 3-d cuboid?

To find the volume of the cube, you multiply its three dimensions: 3cm x 4cm x 5cm = 60 cubic centimeters. Since each centicube is 1 cubic centimeter in volume, you would need 60 centicubes to fill the cube measuring 3cm by 4cm by 5cm.
16 cm 5cm+5cm+3cm+3cm=16cm
15 cm
It is 94 square centimetres.
Area of trapezoid: 0.5*(5+3)*3 = 12 square cm
Well, isn't that a cute little triangle you have there! With those side lengths of 3cm, 5cm, and 3cm, you have what we call a scalene triangle. Each side is a different length, but that just makes it unique and special in its own way. Keep exploring and creating, my friend!
i need help
Rectangle area easiest math for area: 5cm X 3cm = 15cm2
90 cm3
3 x 5 ie 15 cm2
16cm.
It depends on the prism. Is it a triangular prism, a rectangular prism, a pentagonal prism... etc..
5*3 = 15 square cm
