Answer:
913 square centimeters
Step-by-step 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
[tex]SA=5b^2+4[\frac{1}{2}(b)(h)][/tex]
we have
[tex]b=11\ cm\\h=14\ cm[/tex]
substitute
[tex]SA=5(11)^2+4[\frac{1}{2}(11)(14)][/tex]
[tex]SA=605+308=913\ cm^2[/tex]
therefore
Graham will made 913 square centimeters of paint
