Question

Drag each expression to show whether it can be used to find the surface area, volume or neither​

Answer 1

Answer:

Surface area:

$2(12\times 6) + 2(6 \times 8) + 2(8 \times 12)$

$2((12\times 6) + (6 \times 8) + (8 \times 12)$

Volume :

$(12 \times 6 \times 8)$

Neither:

$8(12 \times 6)$

$2(12 \times 6 \times 8)$

$12+6+8$

Step-by-step explanation:

Surface area of the cuboid:

The Surface area of the cuboid = 2(lb) +2(bh)  +2(hl)

Where

l =length of the cuboid

b = Breadth of the cuboid

h = height of the cuboid

So ,

The surface area will be

SA = $2(12\times 6) + 2(6 \times 8) + 2(8 \times 12)$

SA = $2((12\times 6) + (6 \times 8) + (8 \times 12))$

SA  =$2(72+48+98)$

SA = $2(216)$

SA = 432

Volumes of the cuboid:

$Volume = length \times breadth \times height$

Volume = $(12 \times 6 \times 8)$

volume = 576
