 Here is a link to help you! :) TSA


1)
 

v = (bxh'÷2) x h²
    v = (5x3÷2) x 8.5m
    v = (7.5m²) x 8.5m
    v = 63.75m³

2)











v= l x w x h
    v= 20cm x 8cm x 16cm
    v= 2560m³

3) 
 








    v= (bxh'÷2) x h²
    v= (4x8 ÷2) x 6.5cm
    v= 16cm² x 6.5 cm
    v= 104cm³

3/8 = .375 
.375x104cm³ = 39cm³

4)
 







 


 A.O.C (Area of circle)

 aoc = Ï€r²
 aoc = 3.14 x 6 x 6
 aoc = 113.04 cm²

v= aob x h
v= 113.04 x 15
v= 1695.6cm³
