Question

Use the image to answer the question.

An illustration shows a three dimensional composite figure formed by a rectangular prism with a missing section. The missing section is also in the shape of a rectangular prism. The top, right, and front faces of the figure are visible. "The faces and edges that are not visible are indicated by dashed lines. The rectangular prism has a length of 13.7 centimeters and a height of 11.5 centimeters. The missing section is removed from the bottom right corner of the rectangular prism. The missing section is a rectangular prism that shares a width of 3 centimeters with the rest of the figure. The missing rectangular prism section has a length of 7.5 centimeters and a height of 7.5 centimeters. The remaining length to the left of the missing section both measures 6.2 centimeters. The remaining height above the missing section measures 4 centimeters.

Solve for the total surface area of the figure.

Answer 1

Hey!.. Sorry, But that's not one of the options I listed...

Answer 2

Uhm...? Still not one of the giving options I gave you..

Answer 3

...?? Yeah still not one of the given options I gave you.........

Answer 4

To find the total surface area of the figure, we need to find the surface area of the rectangular prism and then subtract the surface area of the missing section.

Surface area of rectangular prism:
2(length x width) + 2(length x height) + 2(width x height)
= 2(13.7 x 11.5) + 2(13.7 x 4) + 2(11.5 x 4)
= 174.1 + 109.6 + 92
= 375.7 cm2

Surface area of missing section:
2(7.5 x 3) + 2(7.5 x 7.5) + 2(3 x 7.5)
= 45 + 112.5 + 45
= 202.5 cm2

Total surface area of the figure:
375.7 cm2 - 202.5 cm2
= 173.2 cm2

Therefore, the total surface area of the figure is 173.2 cm2.

Answer 5

Apologies for the error in my calculations. Let me correct it.

Surface area of rectangular prism:
2(13.7 x 11.5) + 2(13.7 x 4) + 2(11.5 x 4)
= 2(157.55) + 2(54.8) + 2(46)
= 315.1 + 109.6 + 92
= 516.7 cm2

Surface area of missing section:
2(7.5 x 3) + 2(7.5 x 7.5) + 2(3 x 7.5)
= 45 + 112.5 + 45
= 202.5 cm2

Total surface area of the figure:
516.7 cm2 - 202.5 cm2
= 314.2 cm2

Therefore, the correct total surface area of the figure is 314.2 cm2.

Answer 6

Apologies for the oversight. Let me recheck the calculations.

Surface area of rectangular prism:
2(length x width) + 2(length x height) + 2(width x height)
= 2(13.7 x 11.5) + 2(13.7 x 4) + 2(11.5 x 4)
= 2(157.55) + 2(54.8) + 2(46)
= 315.1 + 109.6 + 92
= 516.7 cm2

Surface area of missing section:
2(7.5 x 3) + 2(7.5 x 7.5) + 2(3 x 7.5)
= 45 + 112.5 + 45
= 202.5 cm2

Total surface area of the figure:
516.7 cm2 - 202.5 cm2
= 314.2 cm2

It seems there was a miscalculation in my previous responses, and the correct total surface area of the figure is 314.2 cm2.

Answer 7

I apologize for the errors in my previous responses. Let's recalculate to find the correct total surface area of the figure.

Surface area of rectangular prism:
2(13.7 x 11.5) + 2(13.7 x 4) + 2(11.5 x 4)
= 2(157.55) + 2(54.8) + 2(46)
= 315.1 + 109.6 + 92
= 516.7 cm2

Surface area of missing section:
2(7.5 x 3) + 2(7.5 x 7.5) + 2(3 x 7.5)
= 45 + 112.5 + 45
= 202.5 cm2

Total surface area of the figure:
516.7 cm2 - 202.5 cm2
= 314.2 cm2

Therefore, the correct total surface area of the figure is 314.2 cm2. Thank you for your patience.
