Answer 1

Answer:

1. Vol of cube= Side^3

= 29.791 metre cube.

2. To find the vol of prism...1st we find vol of cuboid..

Thus, vol of cuboid = l×b×h

= 8×15×20/3

= 800 metre cube.

Now, To find vol of prism, simply half the vol of cuboid i.e. 400 metre cube.

Answer 2

Answer:

1. Volume of a cube= side×side×side

Side=3.1m^3

volume = 3.1×3.1×3.1 m^3

= 29.791 m^3

2. Volume of a triangular prism = (B×H×1/2)×L

Breadth =6 2/3ft

Height = 8ft

volume =(1/2×6 2/3×8)×15ft

=80/3×15ft

=400ft

Here is your both the answers
