Question

5 Work out the volume of this prism. Write your answer

a in cm³
b in mm³.
20cm
120cm
30cm
10 cm

Answer 1

a_48000cm^3

b_48000000mm^3

Explanation:

first of all, let's find the base area:

Ab=((b+B)h)/2=((10cm+30cm)20cm)/2=400cm^2

then, to find the volume, we need to multiplicate the base area to the height of the prism:

V=Ab*H=400cm^2*120cm=48000cm^3=48000000mm^3
