Answer : B
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 8 ; w = 4; h = 3
Step 2:
Surface area of given prism = 2(8×4 + 8×3 + 3×4)
= 2(32 + 24 + 12)
= 136 square cm
Answer : C
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 8 ; w = 5; h = 9
Step 2:
Surface area of given prism = 2(8×5 + 8×9 + 5×9)
= 2(40 + 72 + 45)
= 314 square cm
Answer : D
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 4 ; w = 9; h = 2
Step 2:
Surface area of given prism = 2(9×4 + 4×2 + 9×2)
= 2(36 + 8 + 18)
= 124 square cm
Answer : A
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 2 ; w = 3; h = 8
Step 2:
Surface area of given prism = 2(2×3 + 8×2 + 3×8)
= 2(6 + 16 + 24)
= 92 square cm
Answer : D
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 6 ; w = 5; h = 3
Step 2:
Surface area of given prism = 2(6×5 + 6×3 + 3×5)
= 2(30 + 18 + 15)
= 126 square cm
Answer : C
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 3 ; w = 6; h = 8
Step 2:
Surface area of given prism = 2(3×6 + 8×3 + 6×8)
= 2(18 + 24 + 48)
= 180 square cm
Answer : A
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 2 ; w = 8; h = 7
Step 2:
Surface area of given prism = 2(8×2 + 2×7 + 8×7)
= 2(16 + 14 + 56)
= 172 square cm
Answer : B
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 5 ; w = 6; h = 4
Step 2:
Surface area of given prism = 2(5×6 + 5×4 + 6×4)
= 2(30 + 20 + 24)
= 148 square cm
Answer : C
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 6 ; w = 9; h = 6
Step 2:
Surface area of given prism = 2(6×9 + 6×6 + 6×9)
= 2(54 + 36 + 54)
= 288 square cm
Answer : D
Explanation
Step 1:
Using net, the surface area of a rectangular prism = 2(lw + wh + lh); l = 4 ; w = 9; h = 2
Step 2:
Surface area of given prism = 2(4×9 + 4×2 + 9×2)
= 2(36 + 8 + 18)
= 124 square cm
