Answer:
V= 240 sq cm
A= 268 sq cm
Step-by-step explanation:
V= l * w * h
V= 10 * 8 * 3
V= 240 sq cm
A=2(wl+hl+hw)
A=2(8*10 + 3*10 + 3*8)
A= 268 sq cm
<h3>Answer:</h3>
- 28/100 = 7/25
- 100/28 = 25/7
<h3>Explanation:</h3>
The wording "the ratio of A to B" means A/B.
Here, "the ratio of the weight of silicon to the weight of crust" means ...
... (28 tons)/(100 tons)
Canceling common factors (and common units), this is ...
... 28/100 = 7/25
___
Then "the ratio of the weight of crust to the weight of silicon" means ...
... (100 tons)/(28 tons) = 100/28 = 25/7
Answer:
The eqn is incomplete but to simplify we get
6(2a+b),,,no further
