Answer:
Step-by-step explanation:
The surface area of the triangular prism is the sum of its base areas and the lateral area. The total area of the two triangular bases is ...
A = bh = 7(6.1) = 42.7 . . . square units
The lateral area is the product of the perimeter of the base and the length of the prism. The height given for the prism is consistent with it having triangular bases that are equilateral triangles. That is, the unmarked dimension is likely 7 units, so the perimeter is ...
P = 7+7+7 = 21
and the lateral surface area is ...
LA = PL = 21·2 = 42
Then the total surface area of the prism is ...
total area = A + LA = 42.7 +42 = 84.7 . . . square units
__
The volume of a rectangular prism is given by ...
V = Bh
where B is the area of the base, and h is the height. Your prism has a volume of ...
V = (26.25 in²)(4.5 in) = 118.125 in³
Answer: 12 months
Step-by-step explanation:
Given : A tree double in weight in three months.
Since the weight is increasing by growth factor of 2 , therefore its is an exponential growth.
The exponential growth equation is given by :-
(1)
, where A is the initial values , b is the growth factor and x is the time period.
As per given , b= 2
Since the tree doubles in weight in three months, so time period x =
, where t= number of months.
Substitute the value of b and x in (1) , we get
, where y= weight of tree after t months and A is initial weight of tree.
When it will be 1600% of his initial weight , the weight of tree : y= 1600% of A =
At y= 16 A , 
Hence, it will take 12 months to be 1600% in weight.
