Answer:

913 square centimeters

Explanation:

The picture of the question in the attached figure

we know that

The surface area of the toy is equal to the area of five faces of the cube (4 lateral faces plus the base) plus the area of four lateral triangles of the pyramid

so


SA=5b^2+4[(1)/(2)(b)(h)]

we have


b=11\ cm\\h=14\ cm

substitute


SA=5(11)^2+4[(1)/(2)(11)(14)]


SA=605+308=913\ cm^2

therefore

Graham will made 913 square centimeters of paint
