Answer:
are you Philippines ty points
a₂₁ = 41
Step-by-step explanation:
The nth term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then
a₂₁ = 1 + (20 × 2) = 1 + 40 = 41
number of cubes need : (20/3) / (1/27) = 180 cubes
volume of cube = (1/3)^3 = 1/27
volume of prism = 5/3 * 4/3 * 2 = 20/3
<u><em>number of cubes need : (20/3) / (1/27) = 180 cubes</em></u>
