Answer:
Step-by-step explanation:
We have 2 congruent large prisms and one small one.
Volume of a large one= 2*2*14 = 56 cm^3.
Volume of smaller one = 4*3*2 = 24 cm^3.
So volume of the whole prism
= 2*56 + 24
= 136 cm^3.
Surface area of a large one = 3*2*14 + 2*2*5.5 + 2*2*2 = 114
Surface Area of smaller one = 4*3*2 + 2*2*4 = 40
So surface area of the whole prism
= 2 * 114 + 40
= 268 cm^2.
