A square-based pyramid has a base that is a square. All four sides of the base are equal in length, and all angles are right angles. If the apex is centered, all four triangular faces are congruent.

A rectangular-based pyramid has a base that is a rectangle. Opposite sides of the base are equal in length, and all angles are right angles. If the apex is centered, there are two pairs of congruent triangular faces (the faces corresponding to the longer sides are congruent, and the faces corresponding to the shorter sides are congruent).

1. Base Shape: A square-based pyramid has a base with four equal sides, while a rectangular-based pyramid has a base where only opposite sides are necessarily equal.
2. Triangular Faces: If the apex is directly above the center of the base, a square-based pyramid has four congruent (identical) triangular faces. A rectangular-based pyramid, under the same condition, has only two pairs of congruent triangular faces.

Part 2: Pictogram Questions

Let's re-evaluate the pictogram data from the previous interaction to ensure accuracy.
Key: 1 light brown bag = 20 good bags, 1 dark grey bag = 5 spoilt bags.

• Monday: Good: $4 \times 20 = 80$. Spoilt: $1 \times 5 = 5$.
• Tuesday: Good: $3 \times 20 = 60$. Spoilt: $2 \times 5 = 10$.
• Wednesday: Good: $5 \times 20 = 100$. Spoilt: $1 \times 5 = 5$.
• Thursday: Good: $4 \times 20 = 80$. Spoilt: $2 \times 5 = 10$.
• Friday: Good: $3 \times 20 = 60$. Spoilt: $3 \times 5 = 15$.
• Saturday: Good: $4 \times 20 = 80$. Spoilt: $2 \times 5 = 10$.
• Sunday: Good: $3 \times 20 = 60$. Spoilt: $3 \times 5 = 15$.

Question 1: How many spoilt bags were produced in all?

The total number of spoilt bags produced in all is $\boxed{\text{70 bags}}$.

Question 2: What is the total number of good bags for the seven days?

The total number of good bags for the seven days is $\boxed{\text{520 bags}}$.

Question 3: Calculate the average number of good bags produced in one day, correct to the nearest whole number.

Rounding 74.2857 to the nearest whole number gives 74.
The average number of good bags produced in one day to the nearest whole number is $\boxed{\text{74 bags}}$.
