Question

Find the surface area of each prism. Round to the nearest tenth if necessary while doing your calculations as well as in your final answer.

Answer 1

340 units² is right!

Explanation:

I got it correct on my exercise!!

Answer 2

The answer is "340 units²"

Explanation:

In the given question, an attachment file is missing, which can be defined as follows:

`\therefore \tan \theta= (height)/(base)\\\\\to \tan 60^(\circ)=(h)/(3)\\\\\to √(3)=(h)/(3)\\\\\to 3√(3)=h\\\\\to h = 3√(3) units\\\\`

The area of trapezoid prism:

`(a)= (b_1+b_2)h+ph`

value:

`b_1=6 \ units\\b_2=9 \units\\h=10 \ units\\\\\to P=6+9+3√(3)+\sqrt{3^2+(3√(3))^2}\\\\\to P=15+3√(3)+√(9+27)\\\\\to P=15+3√(3)+√(36)\\\\\to P=21+3√(3) \ unit\\\\\bold{ Area= (6+9) * 3√(3)+(21+3√(3))* 10}\\\\\to Area= (15) * 3√(3)+(21+3√(3))* 10\\\\\to Area= 45√(3)+210+30√(3)\\\\\to Area=339.9038\\\\\to Area=340 \ units^2`
