What is the surface area of this rectangular prism?

Mathematics
1 answer:
icang [17]3 years ago

Answer:

96cm

Step-by-step explanation:

For a triangular prism we find the surface area by doing base times height/ length times width, but since we have a triangle we would have to divide the answer we get by 2. Once we get all the sides we then would have to add them all up.

<h3>front                back                                                               top                                                                                                                                                                               </h3>

3X4X1/2         ( HINT: ITS THE SAME AS THE FRONT)      7X5            

12X1/2             6= back                                                          35= top                                

6= front

<h3>Bottom                     side                  <u><em>since we are done finding all</em></u>     </h3>

7X4                           3X7                            <em><u>of the area of the shapes we add </u></em>

28= bottom              21= side                       <u><em>all of them together.</em></u>

Surface area= 6+6+35+28+21= <u><em>96 cm</em></u>

How to estimate $3472 ÷ 680 and solve problem
alisha [4.7K]
If you'd estimate the numbers, it would be $3500÷700. Because if you look at the tenths place, if the number is higher than 5, than the first digit goes up.
$3500÷700=5
Im not very good at explaining.

What’s the answer for m
Archy [21]

Answer:

m\angle D=35.5^o

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

Triangle CDE is an isosceles triangle

because

EC ≅ DE

therefore

m\angle C=m\angle D ----> equation A

Remember that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

m\angle C+m\angle D+m\angle E=180^o ----> equation B

m\angle E=109^o ---> equation C

substitute equation A and equation C in equation B

m\angle D+m\angle D+109^o=180^o\\

2m\angle D=180^o-109^o

m\angle D=35.5^o

How do you compare fractions with the same numerator but different denominator?
Anna007 [38]
To compare fractions with like numerator and different denominators, draw out the numerator and denominators to figure it out. So if you were to figure out 6/10 and 6/17, draw out the denominators and shade in how many of the numerators. Keep in mind to make sure you shade in the same area on the other fraction or else you will get confused.
