Question

I need this for a geo test tomorrow Sa = Surface Area (A bot answered last time)

Answer 1

Answer:

Rect. Prism SA= 251. 75ft²

Cube SA= 8664in²

Cube SA= 6a²

Explanation:

SA= 2(lh+wh+lw)

Cube SA= 6a²

Rect. Prism SA

Assuming length(l)=11.5, width(w)=3.25 and height(h)=6

SA=2(lh+wh+lw)

=2(11.5×6+3.25×6+11.5×3.25)

=2(69+19.5+37.325)

=2×125.875

=251.75ft² (rounding is optional if you like)

Cube SA

SA=6a² (a referring to the edges/sides)

=6× 38²

=6×1444

=8664in²

Hope this helped.
