Answer:

474 Sq m

Explanation:

You have two sides that are 7m x 6m

(7*6)*2 = 84

You have two sides that are 15m x 6m
(15*6)*2 = 180

You have two sides that are 15m x 7m

(15*7)*2 = 210

84+180+210=474

Answer:

474 m²

Explanation:

Surface area of a rectangular prism:

SA = 2(lw + lh + hw)

Given:

  • width (w) = 6 m
  • length (l) = 7 m
  • height (h) = 15 m

⇒ SA = 2(7 · 6 + 7 · 15 + 15 · 6)

= 2(42 + 105 + 90)

= 2(237)

= 474 m²
