Answer:
180 cm²
Step-by-step explanation:
From inspection of the diagram, the surface area is made up of the area of 4 congruent triangles and the area of one square.
Area of a square = x² (where x is the length of one side)
⇒ area of the square = 6² = 36 cm²
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 6 x 12 = 36 cm²
Total surface area = 4 x area of one triangle + area of the square
= 4 x 36 + 36
= 144 + 36
= 180 cm²
P=- 8. Divide both sides by -6.
Answer:
D
Step-by-step explanation:
Firstly, we need to know the number of total possible results. We can do this by placing the first die in horizontal band and the second die in vertical band.
The total number of results would be 36 results.
Now, to get the number of 8s
The possible sums that can give 8 is 2 and 6, 2and 5 and 3 with 4 and 4.
All are possible two times asides the 4 and 4 that could only show one time.
This means as we can have 2 and 6 we can also have 6 and 2
The total number of expected results is thus: 5/36
