Calculate the area of the base.

B=lw

B=3cm*3cm

B=9 cm2

Multiply base times height to get volume.

V=Bh

V=9cm2*10cm

V=90cm3 (volume of square prism)

Find the base.

B=s2

B=2^2

B=4 cm2

Find volume.

V=1/3 Bh

V=1/3 (4cm2) (4.5cm2)

V=1/3 (18 cm3)

V= 6cm3 (volume of pyramid)

Add the volume of the prism and the pyramid together.

90+6

V=96cm3

B=lw

B=3cm*3cm

B=9 cm2

Multiply base times height to get volume.

V=Bh

V=9cm2*10cm

V=90cm3 (volume of square prism)

Find the base.

B=s2

B=2^2

B=4 cm2

Find volume.

V=1/3 Bh

V=1/3 (4cm2) (4.5cm2)
