Step-by-step explanation:
volume of prism = base area × height
= 9/4 * 3/4 * 5/4 = 135/64 cm^3
volume of each cubes = 1/4* 1/4 * 1/4 = 1/64
required no. of cubes
= 135/64/1/64 = 135
66,000*0.15
9,900*5
49,500+66000
The answer is 115.500
I'm not sure if the whole thing is correct, but here is the easier way:
66,000(1+1.15)^5
