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 (<em>a</em><em> </em><em>referring</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>edges</em><em>/</em><em>sides</em><em>)</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em> </em>=6× 38²

=6×1444

=8664in²

Hope this helped.

ololo11 [35]

<u>Answer:</u>

Rising sea levels recorded due to melting glaciers can be considered an observable indication of global warming

<u>Explanation:</u>

The glaciers in the sea are melting due to global warming.This is occurring due to the increase in the global temperature. Year after year, higher temperatures are being recorded and this heat in turn is melting the Arctic glaciers thus adding on to the level of the oceans.

The increased temperature will also disrupt the fauna and floral life. All automobiles don't necessarily have to contribute to global warming. There exist eco-friendly automobiles as well.
