Answer:
B
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = area of triangular face × length
Area of triangle = bh ( b is the base and h the height )
Here b = 6 and h = 8, thus
Area = × 6 × 8 = 3 × 8 = 24 units², thus
V = 24 × 20 = 480 units³ → B
Answer
Find out the value of AM.
To prove
As given
In ABC,
centroid D is on median AM.
AD = x + 5 and DM = 3x – 5.
By using the centroid property
The centroid divides each median in a ratio of 2:1.
Thus D divide the median AM in a ratio of 2:1.
Therefore
(AD) = 2DM
(x + 5) = 6x – 10
5x = 15
x = 3
Now
AM = 3+ 5
= 8 unit
DM = 3 × 3- 5
= 4 unit
AM = AD + DM
= 8 + 4
AM = 12 unit
Therefore the AM is 12 unit.
