Answer:

SA = 470 m²

volume = 494 m³

Step-by-step explanation:

Individual areas

Back = 4 x 19 = 76 m²

Top = 5 x 19 = 95 m²

sloped side = 5 x 19 = 95 m²

base = 8 x 19 = 152 m²

end = (4 x 5) + 1/2(3 x 4) = 26 m²

Total SA = 76 + 95 + 95 + 152 + (2 x 26) = 470 m²

Volume

volume = (4 x 5 x 19) + 1/2(3 x 4 x 19) = 494 m³
