What is the length of the diagonal for the given rectangular prism to the nearest whole unit?
the unit is the length=6, width=5, height=9

A. 8 cm
B.10 cm
C.11 cm
D.12 cm

Answer 1

sl^2= [(1/2) base]^2 + h^2
so
sqrt (36+64)

d = sqrt [36 + 25 + 81]

Answer 2

i don't get it whats the answer

Answer 3

sqrt = square root
so:
sqrt (36+64) = sqrt (100) = 10
and the other one is:
sqrt [36+25+81] = sqrt [142] ≈ 11 or 12
