Question

The triangular prism shown below is 6cm, wide and 4cm deep. The vertical height is 7cm.

What is the length of the side edge, s, of the triangular prism?
Round your answer to the nearest tenth.

Answer 1

: 7.6 cm

Explanation:

Answer 2

Answer: 7.6 cm

Step by step:

Width: w=6 cm

Depth: d=4 cm

Height: h=7 cm

Side edge: s=?

s=sqrt [ (w/2)^2+h^2 ]

s=sqrt [ (6 cm / 2)^2+(7 cm)^2]

s=sqrt[ (3 cm)^2 + 49 cm^2 ]

s=sqrt (9 cm^2+49 cm^2)

s=sqrt (58 cm^2)

s=sqrt(58) cm

s=7.615773106 cm

s=7.6 cm

Answer: 7.6 cm
