Answer:
2(b)h + b²
Step-by-step explanation:
Surface area = area of triangles x 4 + 2(side base)
= 1/2 b h (4) + b*b
= 2 b h + b²
where:
base (b) = 4 cm
side length height (h) = 6 cm
plugin values into the formula:
- 2(b)h + b²
- 2(4)6 + (4)²
- 48 + 16
- 64 cm²
therefore, the formula to calculate surface area
of a square base pyramid = 2(b)h + b²
