Tolong yah pakai cara , no 5,6,7,8 pakai cara, mencari volume

5. V = (luas alas) * t
= ( 1/2 * a * t) * t
= ( 1/2 * 6 * 8) * 18
= 24 * 18
= 432 dm^3

6. V = ( luas alas ) * t
= ( 1/2 * sisi sejajar * t ) * t
= ( 1/2 * ( 5 + 3 ) * 3 ) * 8
= 12 * 8
= 96 cm^3

7. V1 = p * l * t
= 5 * 6 * 4
= 120 cm^3

V2 = ( luas alas ) * t
= ( 1/2 * a * t ) * t
= ( 1/2 * 5 * 3 ) * 6
= 15 * 3
= 45 cm^3

V total = V1 + V2
= 120 + 45
= 165 cm^3

8. V1 = ( luas alas ) * t
= ( 1/2 * a * t ) * t
= ( 1/2 * 3 * 4 ) * 10
= 6 * 10
= 60 cm^3

V2 = ( luas alas ) * t
= ( 1/2 * 5 * 5 ) * 3
= 12,5 * 3
= 37,5 cm^3

V total = V1 + V2
= 60 + 37,5
= 97,5 cm^3
