A rectangular prism, with a capacity of 1.5 cups, the length of the rectangle is 11.5 cm, the width is 8.5 cm what is the surface area? The heights of the triangles is 11.5 cm

There are four triangles here

two triangles with base 11.5 cm and height 11.5cm

two triangles with base 8.5 cm and height 11.5 cm

Surface are = 2x( 1/2 x 11.5 x 11.5) + 2x(1/2 x 8.5 x 11.5)

=> 132.5 + 97.75 = 230.25 cm
