Answer:
RS = 2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
RS² + RT² = TS² , that is
RS² + 6² = 8²
RS² + 36 = 64 ( subtract 36 from both sides )
RS² = 28 ( take the square root of both sides )
RS = =
= 2

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
