Question

Find the total surface area of a building whose dimensions are
25m,15m,40m

Answer 1

Answer:

the total surface of a building is 80m.

Answer 2

Given:-

• Dimensions of a Cuboidal building = 25m, 15m and 40m.

To Find:-

• Total Surface Area of Building

Formula used:-

• TSA of Cuboid = 2(lb + bh + hl)

Solution:-

Here,

• Length (l) = 25m

• Breadth (b) = 15m

• Height (h) = 40m

Using Formula,

$⟹\:TSA \:of \:Cuboid \:= 2(25×15 + 15×40 + 40×25)$

$⟹\:TSA\: of \:Cuboid\: = 2(375 + 600 + 1000)$

$⟹\:TSA\: of \:Cuboid\: = 2 × 1975$

$⟹\:TSA\: of \:Cuboid\: = 3950m²$

Hence, The Total Surface Area of Building is 3950 m².
