Triangular Girder is in the shape of Triangular Prism.

• Volume of metal used in casting it :

⇒ Volume = Volume of Triangular Prism

⇒ Volume = Area of Base Triangle × Length

⇒ Volume = 1/2 × Base × Height × Length

⇒ Volume = 1/2 × 60 m × 90 m × 5 m

⇒ Volume = 30 m × 90 m × 5 × m

⇒ Volume = 13500 m³

⇒ Volume = 13500 × 100 × 100 × 100 cm³

⇒ Volume = 13500000000

⇒ Volume = 135 × 10⁸ cm³

∴ Volume of metal used is 135 × 10⁸ cm³.

Anonymous: You should multiply it 3 times by 100 i.e.100×100×100×volume.

Anonymous: because base and height are also in meter you should also change unit of base and height

ZAYNN: question didn't clearly mention about measurements of triangular sides. so you can't reach to any conclusion. mine is correct too

Anonymous: but it is obvious that it is triangular girder whose measurements can't be in cm

ZAYNN: Why can't measurements be in cm?

Anonymous: Because trianglular girder will be like a bridge.

Anonymous: and cm will be very small unit for girder.

As we know that triangular girder will be in the shape of a prism.

So Formula of volume of girder will be:-

½×Length×Base×height

➠½×60×90×5m³

➠13500m³

➠13500×100×100×100cm³

➠13500000000cm³

•°•Volume of trianglular girder is 13500000000cm³.
