Answer:
Triangular Girder is in the shape of Triangular Prism.
- Triangular Base = 60 m
- Triangular Height = 90 m
- Length of Girder = 5 m
• 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.
because base and height are also in meter you should also change unit of base and height
question didn't clearly mention about measurements of triangular sides. so you can't reach to any conclusion. mine is correct too
but it is obvious that it is triangular girder whose measurements can't be in cm
Why can't measurements be in cm?
Because trianglular girder will be like a bridge.
and cm will be very small unit for girder.

GIVEN:
- Base of trianglular girder is 60m
- Height of trianglular girder is 90m
- Length of trianglular girder is 5m
TO FIND:
- Volume of trianglular girder
SOLUTION:
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.
