What is the surface area of the prism?
1 answer:
*see attachment for diagram of the prism being referred
Answer:
52 m²
Step-by-step explanation:
==>Given:
Rectangular prism as shown in the attachment having the following dimensions=>
length (l) = 4m,
width (w) = 3m
height (h) = 2m
==>Required:
Surface area of the prism = 2 (wl + hl + hw)
==>Solution:
Surface area of the triangular prism = 2 (wl + hl + hw)
= 2*[(3*4) + (2*4) + (2*3)]
= 2*[12 + 8 + 6]
= 2*[26]
S.A = 52 m²
Surface area of the rectangular prism = 52 m²

Answer: 17/18
In words, this is seventeen eighteenths
==========================================
Work Shown:
4/9 + 9/18
8/18 + 9/18 ... see note below
(8+9)/18
17/18
----------------
note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.
The diagram below shows a visual representation of why 4/9 = 8/18.
In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.
