Answer:
106 cm²
Step-by-step explanation:
the surface area is the sum of the areas of the faces of the prism
area of 2 rectangles (left/ right ) = 2 × 7 × 5 = 70 cm²
area of central rectangle = 3 × 7 = 21 cm²
area of 2 congruent triangles = 2 × × 3 × 5 = 3 × 5 = 15 cm²
surface area = 70 + 21 + 15 = 106 cm²
Answer:
Step-by-step explanation:
We can first solve for the face diagonal. That is . Notice this will form a right triangle with the vertical side. We get that the face diagonal = . Now, we can use Pythagorean theorem again to get the straw length:
where s = the straw length.
We can solve that s =
Answer:
UW = EW+UE=2×EW because, EW=UE
7x-2=2×6= 12
7x=14
x=14/7
x=2
<h2>2 is the right answer.</h2>
x + 80 = 180 - (64 + 36)
x + 80 = 180 - 100
x + 80 = 80
x = 0
<h2>0 is the right answer.</h2>
Is this from iready cuz I don’t I’ve had that question before
