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
