The bases of a right prism are rhombii, each with area A = 44cm2. The height of the prism is h = 2.3dm. Find the volume, V, of t
Natali [406]

Step-by-step explanation:

did you make a typo, or do you actually mean dm ?

1 dm = 10 cm

in any case, in a right prism object it does not matter what shape the bases are.

the volume is always

base area × height

so, if you did not make a typo, then

height = 2.3 dm = 23 cm

and the volume of the prism is

44 × 23 = 1012 cm³

but if you did make a typo and

height = 2.3 cm,

then the volume of the prism is

44 × 2.3 = 101.2 cm³
