Question

Can someone help me with math I need help I will attempt to give y’all help too!

Answer 1

Explanation:

Area of triangular pyramid = (1/3)*Base Area * height

`= (1)/(3)*((1)/(2)*b*h) *H`

1) b = 2 in ; h = 6 in and H = 5.8 in

`Area= (1)/(3)*(1)/(2)*2*6*5.8 = 2*5.8 = 11.6 \ in^(2)`

2) b = 3 mi ; h = 4 mi and H = 4 mi

`Area = (1)/(3)*(1)/(2)*3*4*4=2*4 = 8 \ mi^(2)`

3) b = 4 in ; h = 3 in & H = 11 in

`Area=(1)/(3)*(1)/(2)*3*4*11=2*11 = 22 \ in^(2)`

4)b = 8 ft ; h = 15 ft ; H = 19ft

`Area =(1)/(3)*(1)/(2)*8*15*19 = 380 \ ft^(2)`

5) base area = 4.5 mm^2 ; H = 4mm

`Area = (1)/(3)*base \ area * height \\\\\\ =(1)/(3)*4.5 *4 \\\\= 1.5*4 = 6 \ mm^(2)`
