✔ 最佳答案
bottom area= 10 x 8
= 80
side area
= 8 x 9 x 2
= 144
side area
= 10 x 9 x 2
= 180
the surface area is
180 + 144 + 80
= 404
volume
10x8x9
=630

Surface area:
2(10 x 8 + 10 x 4 + 8 x 4)
= 2(80 + 40 + 32)
= 2(152)
= 304 square units
Volume:
10 x 8 x 9
= 80 x 9
= 720 cubic units
2(10 x 8 + 10 x 4 + 8 x 4)
= 2(80 + 40 + 32)
= 2(152)
= 304 square units
Volume:
10 x 8 x 9
= 80 x 9
= 720 cubic units

Surface area = 2(LW+LH+WH)
L= Length W= Width H= Height
Area = 2[(10)(8)+(10)(9)+(8)(9)]
= 2[80+90+72]
Area = 484 sq units
Volume = Length x Width x Height
= (10)(8)(9)
Volume = 720 cubic units
L= Length W= Width H= Height
Area = 2[(10)(8)+(10)(9)+(8)(9)]
= 2[80+90+72]
Area = 484 sq units
Volume = Length x Width x Height
= (10)(8)(9)
Volume = 720 cubic units

Volume will be 10*8*9 = 720 cu. units
Surface Area Will Be 2*8(w)*9(h) [This will calculate surface area of two like sides] +2*10(l)*9(h) [This will calculate the surface area of another two like sides] + 10(l)*8(w) [This Will calculate the base] = 404 sq. units
Surface Area Will Be 2*8(w)*9(h) [This will calculate surface area of two like sides] +2*10(l)*9(h) [This will calculate the surface area of another two like sides] + 10(l)*8(w) [This Will calculate the base] = 404 sq. units

bottom area
= 10 x 8
= 80
side area
= 8 x 9 x 2
= 144
side area
= 10 x 9 x 2
= 180
therefore the surface area is...
180 + 144 + 80
= 404
= 10 x 8
= 80
side area
= 8 x 9 x 2
= 144
side area
= 10 x 9 x 2
= 180
therefore the surface area is...
180 + 144 + 80
= 404
