 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
