Answer:
Volume of square based pyramid = 116.62 cm³
Step-by-step explanation:
Given:
Perimeter of square base = 16.9 cm
Height of pyramid = 19.6 cm
Find:
Volume of square based pyramid
Computation:
Perimeter of square base = 16.9 cm
4[Side] = 16.9
Side = 4.225 cm
Area of square = Side x Side
Area of square = 4.225 x 4.225
Area of square = 17.85 cm²
Volume of square based pyramid = [Area of square][Height of pyramid] / 3
Volume of square based pyramid = [17.85][19.6] / 3
Volume of square based pyramid = 349.86 /3
Volume of square based pyramid = 116.62 cm³

Answer:
40 ft²
Step-by-step explanation:
Divide the figure into 2 rectangles and find their areas.
The area of the smaller rectangle
= 3 × 4
= 12 ft²
The area of the larger rectangle
= (8-4) × 7
= 28 ft²
The area of the figure
= 12 + 28
= <u>40 ft²</u>
