Here's the solution,
the volume of the given figure is :
=》

volume of pyramid :
=》

=》

=》

=》

volume of pyramid = 40 cm³
now, volume of rectangular prism :
=》

=》

=》

volume of rectangular prism = 40 cm³
volume of composite figure = 40 + 40
=》80 cm³
Step-by-step explanation:

Answer:
x = -4
Step-by-step explanation:
Divide both sides by -2.
x= - 8/2
Simplify - 8/2 to -4.
T is the cost of the table. B is the cost of a bench.
b+t=652
b+98=t
t-98+t=652
2t=554
t=277
b=375
