1875cm³
step-by-step explanation:
we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.
20 × 20 × 5 = 2000cm³
now, we need to calculate the volume of the hole.
5 × 5 × 5 = 125cm³
now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.
2000cm³ - 125cm³ = 1875cm³
