Answer:
Step-by-step explanation:
(i) Area of ABCD = (base1+base2)*height/2
= (6+12)*4/2 = 36 cm2
(ii) Volume = Area of ABCD * length = 36 * 25 = 900 cm3
(iii) Total SA = Area of ABCD *2 + 25*5*2 + 6*25 + 12*25
= 72 + 250 + 150 + 300
= 772cm2
If you are multiplying by 100, the decimal will move 2 places to the right.
It moves to the right when multiplying because the number is getting greater, and there are 2 zeroes in 100 so it moves twice.
Answer:
1, √3 , 2
Step-by-step explanation:
Note the side values of a 30-60-90 triangle. The answer is 1, √3 , 2, with 1 being the shortest side, and 2 being the hypotenuse.
For example:
10 , 10√3 , 20 can be the side measurements of a triangle.
