Answer:
Option (D)
Step-by-step explanation:
Surface area of a square pyramid is determined from the formula,
Surface area = Area of the square base + 4(Area of one lateral triangular side)
Area of the base = (Side)²
= 8²
= 64 cm²
Area of one lateral triangle = 
= 
= 32 cm²
Therefore, surface area of the square pyramid = 64 + 4(32)
= 64 + 128
= 192 cm²
Therefore, Option (D) will be the correct option.
Answer:
x = 0
Step-by-step explanation:

Answer:
57.4g
Step-by-step explanation:
32.8g of sugar is needed to make 4 cakes. How much sugar is needed for 7 cakes?
From the above questions, we know that:
4 cakes = 32.8g
7 cakes = x g
Cross Multiply
4 × xg = 7 × 32.8g
x = 7 × 32.8g/4
x = 57.4 g
Therefore, 57.4g is needed for 7 cakes
