Answer:
150 sq.cm
Step-by-step explanation:
total surface area of a cube is
![6a {}^{2}](https://tex.z-dn.net/?f=6a%20%7B%7D%5E%7B2%7D%20)
(where a = measure of each side of the cube)
so, TSA = 6 × 5 × 5 = 150 sq.cm
Answer:
whats CDA716?
Step-by-step explanation:
Answer:
it should be 1/2
Step-by-step explanation:
because the sequence is going down by 0.05 each time;
7/10= 0.70
13/20= 0.65
3/5= 0.6
11/20= 0.55
so to continue the pattern,
1/2= 0.5
Answer:
Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3.
Step-by-step explanation:
The rectangle ABCD is dilated by a factor of 3 to get the rectangle WXYZ whose area is found to be 72 cm².
Let the dimensions of the dilated rectangle WXYZ are a cm by b cm.
So, ab = 72 ........... (1)
Now, the dimensions of the original rectangle are 3 times lesser than the dimensions of rectangle WXYZ.
So, the area of rectangle ABCD will be
cm² {from equation (1)}
Therefore, Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3. (Answer)
