106.79 mi3

67.98 mi3

213.57 mi3

135.96 mi3

Answer 1

Length times width times height

Answer 2

Plug it into the formula please

Answer 3

sorry ....427..

Answer 4

not quite, length*width*height would only work if the prism were rectangular

since the base is a triangle, we need to find the area of the triangular base first

the base is a triangle with height = 6.4 and base = 4.7
area of the triangle = (1/2)(6.4)(4.7)

then multiply by the height of the prism to find volume
volume = (1/2)(6.4)(4.7)(14.2)

Answer 5

the general formula for the volume of a prism is b*h where h is height and b is the area of the base

Answer 6

oh 213.56

Answer 7
