Answer:
d) 405 = 15 times 4.5 times h
The height of the prism 'h' = 6 inches
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given Volume of prism
V = 405 cubic inches
<em>Given length of the prism </em>
<em> L = 15 inches</em>
<em>Given width of the prism</em>
<em> W = 4.5 inches </em>
<em>The volume of the prism </em>
<em> V = l w h</em>
405 = 15 ×4.5× h
405 = 67.5 h
Dividing '67.5' on both sides , we get
h = 6 inches
<u>Final answer:-</u>
The height of the prism 'h' = 6 inches

The distance AD is found by Pythagoras theorem, with
AD=sqrt(BC^2+(AB-DC)^2)=sqrt(21^2+2^2)=sqrt(441+4)=sqrt(445)
=
21.095 (to the third decimal place)
